Fix IME tray bubble (and other tray bubble views).

This was broken by 17ab8262e8e13c1ace5 which stopped explicitly painting
a background for bubble contents views.

The symptom I observed is a black background (due to the layer being
opaque and painting nothing). This should also fix the subpixel text
corruption shown in the bug.
