Bug 90508 – [Shadow] A 'selectstart' event fired on distributed nodes should not be stopped at shadow boundary of the parent shadow host.

• Status: RESOLVED
• Resolution: FIXED
• Component: UI Events

[Hayato Ito]

Suppose the following DOM tree:

  <div id='host'>
    [shadow-root]
       <content></content>
    <div id='distributed-node'></div>
  </div>

Then, an event of 'selectstart', which is one of the events which mut always be stopped at the nearest shadow boundary [*1], is dispatched on #distributed-node. Let's assume it is bubbling up.

In that case, #host should receive the event. But the event is wrongly stopped at the shadow boundary of #host. #host won't receive the event.

This is not a specific issue to 'selectstart' event. See bug 90436 also.

wip.

I have to merge this patch with bug 90436.

In theoretically, both patches are independent of each other.
But there wil be conflicts in code. I have to resolve it.
