REGRESSION (r245672): <select> dropdown with text-rendering: optimizeLegibility freezes Safari
​https://bugs.webkit.org/show_bug.cgi?id=202198

Reviewed by Tim Horton.

Source/WebKit:

NSFont has a bug where passing "auto" to kCTFontOpticalSizeAttribute
causes an exception to be thrown. We don't catch the exception, so we
pop up back to the runloop, which confuses the UI process.

The solution is twofold: 1) Workaround the bug by passing the font size
to kCTFontOpticalSizeAttribute instead, and 2) catch any exceptions that
this part of the code might throw.

Stop 'using namespace SVGNames' and 'using namepace HTMLNames' in
files generated by make_names.pl. Just use fully-qualified names.

There is some overlap between the two namespaces, so this is a
prerequsite for doing more aggressive unified source bundling in bindings.

Invoke callbacks registered by requestIdleCallback
​https://bugs.webkit.org/show_bug.cgi?id=202824

Reviewed by Antti Koivisto.

Invoke callbacks registered by requestIdleCallback unless it's canceled.

To do this, this patch introduces WindowEventLoop class, which represents the HTML5 event loop:
​https://html.spec.whatwg.org/multipage/webappapis.html#window-event-loop

Because each and only each agent cluster is meant to have its own window event loop, this class will be shared
across multiple documents of the same registrable domain:

Back/Forward cache does not work after doing a favorite navigation

<rdar://problem/56126911>

Reviewed by Antti Koivisto.

Source/WebCore:

When a subframe goes into the page cache, make sure we null out the opener
link of any windows that were opened by this frame. This matches what would
happened if this frame were closed.

Covered by the following API tests:
ProcessSwap.PageCacheAfterProcessSwapByClient
ProcessSwap.OpenerLinkAfterAPIControlledProcessSwappingOfOpener

• loader/FrameLoader.h:

Source/WebKit:

When a process-swap was forced by the client, we would always close the page in the previous
process after navigating. This would prevent leveraging the back/forward cache when navigating
back after such a process-swap. The reason we were doing this is that other pages may have
opener link to this page and closing the page was an easy way to break this opener link.

To address the issue, we no longer close the previous page when a process-swap is forced by the
client. Instead, we make sure to disconnect the frames' openees from their opener then the opener
enters the page cache.

Stop taking a parameter indicating if we allow the processes to enter the

cache unconditionally. If the caller does not want this processes in the page
cache, they can clear the process cache afterwards.
