Mention this in the CL description too, assuming that it's a fix for some bug?

Nope. This is for this CL. Until now, we have only intercepted keyboard and
mouse events, and for those, we have always had associated GdkWindow's. In this
case, however, for MappingNotify event, we get the XID of the root window, and
we don't have a GdkWindow associated with this.

         // Always dispatch key events to the input method first, to make sure
         // that the input method's hotkeys work all time.
