- Remove script_shift_attributes preference and related test, warning
message and parsing.
- Do not remove subscriptshift/supscripshift atoms, since they are
still needed for nsTreeSanitizer.

- nsMathMLmencloseFrame continues to implement the radical notation for

refactor our code so that msqrt/mroot share the same implementation.

This fixes the original case by adding an extra error reason which is used when
the specifier could be bare and and only warning about relative URLs in this
case.
The same problem happens with import maps enable where "./foo.js" produces an
error about it being a bare specifier, which it's not. For that case make
ParseURLLikeImportSpecifier return a ResolveResult and use the same approach.

Previously, we supported an action on text leaf and image accessibles if an ancestor was a link or was clickable.
However, we didn't support it on any other kind of descendant, nor could clients differentiate between a click handler on the descendant itself vs an action propagated because of an ancestor.
In addition, the click was performed on the ancestor element itself, rather than bubbling up to the ancestor.
This was probably never a real problem given the limited scope, but it meant that the actual event target was lost.
This has been replaced by a "click ancestor" action supported on all descendants of ancestors providing an action.
The click is dispatched to the descendant and bubbles up to the ancestor.
Aside from consistency and the ability to differentiate the action, this allows clients to stop relying on simulating clicks themselves to directly target a descendant.
This avoids problems caused by obscured web elements, obscured browser windows and other weird screen coordinate issues.
It thus fixes several problems reported by NVDA screen reader users.

Implements https://github.com/whatwg/html/issues/6962 . Improves performance
when <meta charset> occurs in head but after the first kilobyte and aligns
behavior better with WebKit and Blink.
The main change is to avoid reloads when meta appears within head but
after the first kilobyte. Prior to this change, Gecko reloaded in that
case (in compliance with the spec!) even though WebKit and Blink did not.
Differences from WebKit and Blink:
* WebKit and Blink honor <meta charset> in <noscript>. This implementation
does not.
* WebKit and Blink look for meta as if the tree builder was unaware of
foreign content. This implementation is foreign content-aware. This
makes a difference for CDATA sections that contain a > before the meta
as well as style and script elements within foreign content. This could
happen if the CDATA section that has mysteriously been introduced around
a what looks like a meta tag also contains another prior tag-looking
run of text.
* This implementation processes rel=preload and speculative loads that are
seen before <meta charset> has been seen. WebKit and Blink instead first
look for the meta and rewind before starting speculative parsing.
* Unlike WebKit, if there is neither an honored meta nor syntax resembling
an XML declaration, detection from content takes place (as in Blink).
* Unlike Blink, if there is neither an honored meta nor syntax resembling
an XML declaration, the detection from content is not dependent of network
buffer boundaries.
* Unlike Blink, detection from content can trigger a reload at the end of
the stream if the guess made at that point differs from the first guess.
(See below for the definition of the input to the first guess.)
Differences from the old spec and Gecko previously:
* Meta inside script and RCDATA elements is no longer honored.
* Late meta is now ignored and no longer triggers a reload.
* Later meta counts as early enough meta: In addition to the previous
meta within the first 1024 bytes, now a meta that started within the first
1024 bytes counts as early enough. Additionally, if by then there hasn't
been a template start tag and head hasn't ended, meta occurring before the
earlier of the end of the head or a template start tag counts as early
enough.
* Meta now counts as not-late even if the encoding label has numeric
character reference escapes.
* Syntax resembling an XML declaration longer than a kilobyte is honored if
there is no honored meta.
* If there is neither an honored meta nor syntax resembling an XML declaration,
the initial chardetng scan is potentially longer than before: the first 1024
bytes, the token spanning the 1024-byte boundary if there is such a token,
and, if by then head hasn't ended and there hasn't been a template start tag
until the end of the template start tag or the end of the token that causes
head to end, ever comes first. However, if the token implying the end of the
head is a text token, bytes only to the end of the previous non-text token is
considered. (This definition avoids depending on network buffer boundaries.)
* XML View Source now uses the code for syntax resembling an XML declaration
instead of expat for extracting the internal encoding label.
Reftest are added as both WPT and Gecko reftests in order to test both http:
and file: URL scenarios. The Gecko tests retain the WPT <link> tags in order
to use the exact same bytes.
An encoding declaration has been added to a number of old tests that didn't
intend to test the new speculation behavior especially in the context of
https://bugzilla.mozilla.org/show_bug.cgi?id=1727750 .

This patchs adds new error messages which are extending existing ones,
providing extra information to the user.
A webconsole mochitest is added in the following patch of this stack.
Differential Revision: https://phabricator.services.mozilla.com/D131889
This patch does:
- add to ExtensionBrowser two new data members to keep track of value for the browser.runtime.lastError and if it was checked while
the chrome compatible callback was being executed
- add to ExtensionBrowser 3 new methods to set, get and clear the lastError value
- add a reference to the ExtensionBrowser to all API namespaces and API objects classes, because it has to be then propagated to the
ChromeCompatCallbackHandler instances that are being attached to the promise result of the async API methods calls if the caller did
pass the optional callback parameter
- tweak the ChromeCompatCallbackHandler class to set the lastError value before calling the callback in ChromeCompatCallbackHAndler::RejectedCallback
and then clear it after the call has been completed and report it to the console if it wasn't checked
- change the ExtensionRuntime::GetLastError methhod to restrieve and return the value from the ExtensionBrowser instance
