Control OnTitlebar ./. OnWindow

On concurrent shortcuts OnTitlebar implies OnWindow and was so
far resolved to OnWindow while OnTitlebar is the more precise
condition.

This also requires to exclude buttons from the titlebar context,
ie. pass the position to the getContext function on press events

BUG: 1035

The patch depends on the patch to correctly resolve the tab under the
mouse since we're now passing the actual subwindows around
