SUMMARY

When dragging a selection rectangle inside a folder view, it sometimes gets stuck.
It also wont select any items.


STEPS TO REPRODUCE
1. Add folder view widget and set it to point to a folder with enough files to show scrollbar
2. Drag around the widget to create selection
3. In some folders, like Music when selected in "Places panel item" section, it wont select anything
4. But with custom selection it does???
5. If user holds down mouse long enough for the drag effect to start, then moves mouse around, the selection effect gets stuck

OBSERVED RESULT
Everything is horrible

EXPECTED RESULT
Selection would select and not get stuck

ContainmentLayoutManager: send recursive mouse release events too

In order to be sure to not leave any hanging mouse event,
such as the folderview rubberband stuck in selection mode,
when we are sending a recursive ungrab, fist send a recursive mouse release
event as well, to make sure any item that might have an internal state
of mouse pressed will reset it
