// that the window itself is always in the list, and an outer window's list will
// also contain all inner window objects that are still in memory (and in
// reality all inner window object's lists also contain its outer and all other
// inner windows belonging to the same outer window, but that's an unimportant
// side effect of inheriting PRCList).

*
* @param aDialog true when called from variants of OpenDialog. If this is
* true, this method will skip popup blocking checks. The aDialog
* argument is passed on to the window watcher.
*
* @param aCalledNoScript true when called via the [noscript] open()
* and openDialog() methods. When this is true, we do NOT want to use
* the JS stack for things like caller determination.
*
* @param aDoJSFixups true when this is the content-accessible JS version of
* window opening. When true, popups do not cause us to throw, we save
* the caller's principal in the new window for later consumption, and
* we make sure that there is a document in the newly-opened window.
* Note that this last will only be done if the newly-opened window is
* non-chrome.
*
* @param aNavigate true if we should navigate to the provided URL, false
* otherwise. When aNavigate is false, we also skip our can-load
* security check, on the assumption that whoever *actually* loads this
* page will do their own security check.
*
* @param argv The arguments to pass to the new window. The first
* three args, if present, will be aUrl, aName, and aOptions. So this
* param only matters if there are more than 3 arguments.
*
* @param aExtraArgument Another way to pass arguments in. This is mutually
* exclusive with the argv approach.
*
* @param aLoadState to be passed on along to the windowwatcher.
*
* @param aForceNoOpener if true, will act as if "noopener" were passed in
* aOptions, but without affecting any other window
* features.
*
* @param aReturn [out] The window that was opened, if any. Will be null if
* aForceNoOpener is true of if aOptions contains
* "noopener".
*
* Outer windows only.
