Why is there a MouseoverMask that stops me clicking on screen elements?

YUI 3.16.0 (build 76f0e08) var n=e.Node.create('<div id="MouseoverMask" class="End-0 Start-0 T-0 B-0"></div>'), n.appendTo(i.body)


Dunno, that's a mystery!

I asked my car salesman, why does this car have an ashtray in the arm rest. He said because it does! See the similarity?
