Prevent browser-side hit testing when page popup is selected
When any form of cross-process frames are enabled, the browser process
locks mouse input to a RenderWidgetHostView while a mouse button is
being held down. This also applies to page popups, which causes a
problem on Linux when a user drag-selects a drop-down menu from a
<select> element, because the popup does not receive any input until
the button is released.
This changelist exempts popup RenderWidgetHostViewAuras from browser-
side hit testing, ignoring mouse capture.
