Subject: [PATCH] Resolves: rhbz#1351224 wayland grab related crashes
only one popup active at a time. Try and find the right path through the
uncanny valley which allows popups to appear, to get all mouse input that
happens to them, forward keyboard input to their parents, dismiss when the
mouse is clicked outside them and not crash if another popup wants to appear
to replace it
gtk3: XEmbed isn't going to happen
Change-Id: I7a7589a159a7fccdc224262bf5f91f8d98f5f619
(cherry picked from commit fe7b8bc9fdb57087ba9daa22cdec77d735eb71cd)
gtk3: if a popup is withdrawn close the popup
we don't always get the click that causes the popup
to be withdrawn when the mouse is clicked outside
the application during a grab
Change-Id: I2dbef23813972ebd75c8899711a2d1309110f968
(cherry picked from commit 1190e7385291fb0e6cd3505e88e589c80b02db00)
