alt+tab does not work with drag and drop

Use Case:

Dragging movie/audio files from nautilus to totem.

Steps to Reproduce:

1. open totem media player full screen
2. open nautilus full screen
3. browse to media files
4. select some media files (e.g. a movie file) and move it to start a drag and drop operation
5. press Alt+Tab

Observations:

Nothing happens.

Expected Results:

Alt+Tab should allow the user to switch tasks and preserve the drag state, so the user can drag files from one application to another.

Notes:

Drag and drop works if the applications are tiled to the left/right of each other, or if they are windowed so it should work when they are full screen.
