------- Additional Comments from Jay Campan <jcampan at google.com>
There was a crasher that could happen when a select popup is opened and a page
navigates.
The cause is that the PopupMenuContainer still exists but the PopupMenuClient
has been deleted, and then when hidden the popup would try to access the
PopupMenuClient, causing the crasher.
We now clear the reference to the PopupMenuClient when the popup is deleted and
we don't access it.
