[regression] Selecting an item of the BFB quicklist when the dash is open, causes it to hide

Bug Description

1) Open the unity dash
2) right-click on the BFB
3) select a quicklist item to open a specified lens

Expected result:
4) The selected lens is opened in the dash

Actual result:
4) The dash hides itself (even if it is actually open, since the launcher is still blurred).

Clicking again over one quicklist item, makes the dash to show again (and select the correct lens)

This bug was fixed in the package unity - 6.4.0-0ubuntu1
