When installing/uninstalling the clip on native buttons they would not be painted properly. This is the case for animations, such as the dangerous download item animation.

(For some unclear reasons this would happen only in aero and only in a popup browser frames.)
Explicitly asking for a repaint when setting the clip fixes it.

BUG=23087
TEST=Start a dangerous download from a popup (sorry, I don't have any public URL to repro). The dangerous download should display properly in the download shelf.
