Abort drag when involved window(s) vanish
Patch status: needinfo
Patch by Tony Crisci
When in a dragging state induced by `drag_pointer`, abort (rather than send `DRAG_CANCEL` result) on UnmapNotify. Fixes an issue that caused i3 to crash when a user is dragging or resizing a floating window that becomes destroyed.
