When native window requests button presses request other button related events

Browse Source 
We need to do this because otherwise the implicit button grab for this
(native) window will not deliver the button events not selected for
by this window. This is a problem because non-native child windows may
select using a wider event mask, and we can't emulate these events if we
don't get the native events.

Fixes bug #607508
