  // functions in invokeGuardedCallback, and the production version of
  // invokeGuardedCallback uses a try-catch, all user exceptions are treated
  // like caught exceptions, and the DevTools won't pause unless the developer
  // takes the extra step of enabling pause on caught exceptions. This is
  // unintuitive, though, because even though React has caught the error, from
  // the developer's perspective, the error is uncaught.
  //
  // To preserve the expected "Pause on exceptions" behavior, we don't use a
  // try-catch in DEV. Instead, we synchronously dispatch a fake event to a fake
  // DOM node, and call the user-provided callback from inside an event handler
  // for that fake event. If the callback throws, the error is "captured" using
  // a global event handler. But because the error happens in a different
  // event loop context, it does not interrupt the normal program flow.
  // Effectively, this gives us try-catch behavior without actually using
  // try-catch. Neat!

 *   responder view, and no other view.
 * - While touches are still occurring, the responder lock can be transferred to
 *   a new view, but only to increasingly "higher" views (meaning ancestors of
 *   the current responder).
 *
 * Responder being granted:
 * ------------------------
 *
 * - Touch starts, moves, and scrolls can cause an ID to become the responder.
 * - We capture/bubble `startShouldSetResponder`/`moveShouldSetResponder` to
 *   the "appropriate place".
 * - If nothing is currently the responder, the "appropriate place" is the
 *   initiating event's `targetID`.
 * - If something *is* already the responder, the "appropriate place" is the
 *   first common ancestor of the event target and the current `responderInst`.
 * - Some negotiation happens: See the timing diagram below.
 * - Scrolled views automatically become responder. The reasoning is that a
 *   platform scroll view that isn't built on top of the responder system has
 *   began scrolling, and the active responder must now be notified that the
 *   interaction is no longer locked to it - the system has taken over.
 *
 * - Responder being released:
 *   As soon as no more touches that *started* inside of descendants of the
 *   *current* responderInst, an `onResponderRelease` event is dispatched to the
 *   current responder, and the responder lock is released.
 *
 * TODO:
 * - on "end", a callback hook for `onResponderEndShouldRemainResponder` that
 *   determines if the responder lock should remain.
 * - If a view shouldn't "remain" the responder, any active touches should by
 *   default be considered "dead" and do not influence future negotiations or
 *   bubble paths. It should be as if those touches do not exist.
 * -- For multitouch: Usually a translate-z will choose to "remain" responder
 *  after one out of many touches ended. For translate-y, usually the view
 *  doesn't wish to "remain" responder after one of many touches end.
 * - Consider building this on top of a `stopPropagation` model similar to
 *   `W3C` events.
 * - Ensure that `onResponderTerminate` is called on touch cancels, whether or
 *   not `onResponderTerminationRequest` returns `true` or `false`.

/**
 * A note about event ordering in the `EventPluginRegistry`.
 *
 * Suppose plugins are injected in the following order:
 *
 * `[R, S, C]`
 *
 * To help illustrate the example, assume `S` is `SimpleEventPlugin` (for
 * `onClick` etc) and `R` is `ResponderEventPlugin`.
 *
 * "Deferred-Dispatched Events":
 *
 * - The current event plugin system will traverse the list of injected plugins,
 *   in order, and extract events by collecting the plugin's return value of
 *   `extractEvents()`.
 * - These events that are returned from `extractEvents` are "deferred
 *   dispatched events".
 * - When returned from `extractEvents`, deferred-dispatched events contain an
 *   "accumulation" of deferred dispatches.
 * - These deferred dispatches are accumulated/collected before they are
 *   returned, but processed at a later time by the `EventPluginRegistry` (hence the
 *   name deferred).
 *
 * In the process of returning their deferred-dispatched events, event plugins
 * themselves can dispatch events on-demand without returning them from
 * `extractEvents`. Plugins might want to do this, so that they can use event
 * dispatching as a tool that helps them decide which events should be extracted
 * in the first place.
 *
 * "On-Demand-Dispatched Events":
 *
 * - On-demand-dispatched events are not returned from `extractEvents`.
 * - On-demand-dispatched events are dispatched during the process of returning
 *   the deferred-dispatched events.
 * - They should not have side effects.
 * - They should be avoided, and/or eventually be replaced with another
 *   abstraction that allows event plugins to perform multiple "rounds" of event
 *   extraction.
 *
 * Therefore, the sequence of event dispatches becomes:
 *
 * - `R`s on-demand events (if any)   (dispatched by `R` on-demand)
 * - `S`s on-demand events (if any)   (dispatched by `S` on-demand)
 * - `C`s on-demand events (if any)   (dispatched by `C` on-demand)
 * - `R`s extracted events (if any)   (dispatched by `EventPluginRegistry`)
 * - `S`s extracted events (if any)   (dispatched by `EventPluginRegistry`)
 * - `C`s extracted events (if any)   (dispatched by `EventPluginRegistry`)
 *
 * In the case of `ResponderEventPlugin`: If the `startShouldSetResponder`
 * on-demand dispatch returns `true` (and some other details are satisfied) the
 * `onResponderGrant` deferred dispatched event is returned from
 * `extractEvents`. The sequence of dispatch executions in this case
 * will appear as follows:
 *
 * - `startShouldSetResponder` (`ResponderEventPlugin` dispatches on-demand)
 * - `touchStartCapture`       (`EventPluginRegistry` dispatches as usual)
 * - `touchStart`              (`EventPluginRegistry` dispatches as usual)
 * - `responderGrant/Reject`   (`EventPluginRegistry` dispatches as usual)

        // Restarting too aggressively is also not good because it starves out any
        // intermediate loading state. So we use heuristics to determine when.

        //
        // If nothing threw a Promise or all the same fallbacks are already showing,

        // those trigger a fallback, then don't suspend/restart. We want to ensure
        // that we can show the initial loading state as quickly as possible.
        //
        // If we hit a "Delayed" case, such as when we'd switch from content back into
        // a fallback, then we should always suspend/restart. Transitions apply
        // to this case. If none is defined, JND is used instead.
        //
        // If we're already showing a fallback and it gets "retried", allowing us to show
        // another level, but there's still an inner boundary that would show a fallback,
        // then we suspend/restart for 500ms since the last time we showed a fallback
        // anywhere in the tree. This effectively throttles progressive loading into a
        // consistent train of commits. This also gives us an opportunity to restart to
        // get to the completed state slightly earlier.
        //
        // If there's ambiguity due to batching it's resolved in preference of:
        // 1) "delayed", 2) "initial render", 3) "retry".

  // main reasons this is so complicated.
  //
  // First, Legacy Mode has different semantics for backwards compatibility. The
  // primary tree will commit in an inconsistent state, so when we do the
  // second pass to render the fallback, we do some exceedingly, uh, clever
  // hacks to make that not totally break. Like transferring effects and
  // deletions from hidden tree. In Concurrent Mode, it's much simpler,
  // because we bailout on the primary tree completely and leave it in its old
  // state, no effects. Same as what we do for Offscreen (except that
  // Offscreen doesn't have the first render pass).
  //
  // Second is hydration. During hydration, the Suspense fiber has a slightly
  // different layout, where the child points to a dehydrated fragment, which
  // contains the DOM rendered by the server.
  //
  // Third, even if you set all that aside, Suspense is like error boundaries in
  // that we first we try to render one tree, and if that fails, we render again
  // and switch to a different tree. Like a try/catch block. So we have to track
  // which branch we're currently rendering. Ideally we would model this using
  // a stack.
