Bug 83474 – [Chromium] External popup menus should support early cancelation

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Jay Civelli]

In Chromium for Mac and Android, we can end up in cases where we end up with 2 select popups showing (if the user presses a select and then quickly presses another before the 1st one has shown).
We need a way for the browser to cancel a select popup early to prevent that case.

Hmm, can you point me to the code that might refuse to create a popup?  The implementation that I found for createExternalPopupMenu() [1] looks like it will always create a new one, but sometimes destroy the old one (if the DCHECK fails).  Does this patch assume a Chromium change as well?

Yes there is an CL on the Chromium side to make this work:

Ok, looks good when coupled with the Chromium CL.

tkent, can you double check for an official review, since I'm not a reviewer?

nit: This else clause contains two physical lines.  So we need to enclose it with {}.
