Description David Saff CLA 2005-10-05 15:45:47 EDT 
A tab from view can be dragged into the fast view area to be changed into a fast
view.  Before M2, it was possible to drag the fast view icon back to a tab group
to turn the fast view back into a normal view.  In M2, this doesn't happen: the
cursor doesn't change to indicate that the view has been "picked up", and some
weird view-like artifacts appear (see attached screenshot).  The "Fast View"
checkbox on the icon's context menu still works, however.
