Code review comment for lp:~mardy/unity-2d/spread-a11y-geometry

I see the issue I raised earlier was raised by Michaŀ in https://code.launchpad.net/~mardy/unity-2d/spread-a11y/+merge/78593
That was your answer:
"The first issue with the mouse hover could be avoided, but I chose it this way because I think it's more intuitive than requiring to click outside -- and indeed, if you zoomed into a workspace and then move the mouse out of it, you probably want to dismiss it (and if not, it's easy enough to bring it back to zoomed state). Let me know if I should change this."

I'll consult with design now.
