gtk: Hide the status bubble when the mouse nears it.
This isn't as slick as other platforms, in that the bubble
just slides down and gets cropped instead of sliding down out
of the browser window -- doing the latter will probably
require reparenting the bubble into its own window when we
want to move it.
BUG=18311
TEST=ran "nc -l -p 8080", went to localhost:8080, and made sure that the bubble ran away with both LTR and RTL languages
