Clarify that modal dialogs escape inertness of ancestors.

[emilio]

• At least two implementers are interested (and none opposed):
  • Gecko
  • WebKit
  • Chromium
• Tests are written and can be reviewed and commented upon at:
  • Test mentioned in inert on an ancestor of modal dialog #7808 needs a trivial expectation change.
• Implementation bugs are filed:
  • Chrome: https://bugs.chromium.org/p/chromium/issues/detail?id=1323680
  • Firefox: N/A
  • Safari: N/A
  • Deno (only for timers, structured clone, base64 utils, channel messaging, module resolution, web workers, and web storage): N/A
  • Node.js (only for timers, structured clone, base64 utils, channel messaging, and module resolution): N/A

(See WHATWG Working Mode: Changes for more details.)

Looks good, thanks!

The commit should have "Closes #7808." in the message.

§6.3.2 still says "all its flat tree descendants are to be made inert". I think this should exclude subtrees of nodes that "escape inertness".

This seems like a good idea, even though that text is just a summary. Emilio, can you make this update?

[emilio]

Done! And sorry @Loirooriol, I had missed the previous notification.

[domenic]

Thanks all!

I forgot to say: please remember to update the tests, and report back to this thread when that's done.
