AX: <details> element should allow expand/close through AX API

[chris fleizach]

VoiceOver needs a way to expand/collapse (either AXPress or make expanded writable) this group along with a notification when it is expaneded or collapsed (probably ValueChanged)

Looks good to me, just a minor comment below for consideration before landing

Maybe you can put downcast<HTMLDetailsElement>(node()) in a variable so that you don't have to repeat that three times. Or just downcast<HTMLDetailsElement>(node())->isOpen(). Or both :)

details-summary.html times out on all bots.

[Brent Fulgham]

This is timing out everywhere. Can you please fix it? Or should we deactivate the test?

Perhaps there's an issue with the notifications and finishJSTest() is never called? Maybe some missing bits in WKTR, Chris?

I would have written this as:

if (is<HTMLDetailsElement>(node())) {
    auto& details = downcast<HTMLDetailsElement>(*node());
    if (expand != details.isOpen())
        details.toggleOpen();
}
