DOM: EventListener invocation order during AT_TARGET phase

merge_pr_12

Fixes click on inline element embedded in anchor inside

breaks anchor.

Previous to this CL, clicking on an inline element embedded in an anchor placed
inside a

tag will expand the

section instead of navigating to
the anchor's href. However, when the anchor is placed outside of

,
it behaves correctly.

The error is caused by DOMActivate event generated by the inline element. As
DOMActivate bubbles up, it bypasses the anchor's event handler, reaches the

, and is handled there. Once DOMActivate is handled, the original click event stops propagating and terminates. This behavior, however, differs from when the anchor tag is placed outside of the summary. DOMActivate isn't handled, and the original click event keeps bubbling up till it's handled by the anchor.

DOMActivate event is deprecated:
https://developer.mozilla.org/en-US/docs/Web/API/Element/DOMActivate_event.
However, since blink still has code that depends on it, replacing it is outside
of the scope for this fix. Instead, this fix is for the anchor element to
handle the DOMActivate event as it bubbles up. The anchor event handler checks
the underlying event of DOMActivate and handles it if it's a click.

I also looked at an alternative fix by trying to prevent the DOMActivate event
from bubbling up. But calling event.stopPropagation() doesn't work as the
EventDispatcher::DispatchEventPostProcess doesn't check this status.

Don't assume sync dispatch of iframe load event in tests

Blink and WebKit dispatch the load event of the iframe synchronously,
whereas Gecko and (currently) the spec assume it's async. This causes
a hang in some tests using this helper library because in Gecko a
subsequent load ends up running in the event dispatch of the initial
load event, and so the load event is suppressed and the tests are
unable to complete. In other browsers the event is not suppressed and
so the tests run.

Avoid this by ensuring that the event loop always spins after the
iframe load.

Remove size_x and size_z from VRStageParameters

The notion of a simple "size" for Stage Parameters/bounded was a WebVr
concept that did not carry over to WebXr. To simplify the mojom, move
the "conversion" of square stages (for those runtimes that only support
giving size x/z) down into a utility function in the device process.
