Dash - dragging a file outside of the Desktop Dash should close the Dash

Bug Description

If a user drags a file past the border of the Desktop Dash, the Dash should disappear. This allows the user to continuing dragging and then drop the file onto a window that was occulted by the desktop dash.

Desired resolution:

- The Dash should not close until the user drags a item *outside* of the Dash area
- This applies to all Dash Lenses, not just the File Lens

This appears to already be implemented in natty (with the latest unity 3.8.14-0ubuntu1~natty1). Or am I imagining things?

But see also bug 773892 which is not yet resolved.

And it seems the current behaviour already implemented in natty actually solves this bug better than the "Desired resolution" in the description... ?

This bug was fixed in the package unity - 4.18.0-0ubuntu1
