[2.2][DUP] Grid/tree mouseover highlight does not dissapear when scrollbar is present

The grid and tree mouseover highlight does not dissapear when you move out of the panel over a scrollbar.

This happens in Firefox only.

Steps to reproduce:

Make a grid or treepanel scroll and move the mouse over some items and rapidly move it out of the panel going over the scrollbar.

Duplicate of this (GridPanel) + this (TreePanel) post.

ps. It also happens with DataView, but that one can't be fixed the same way, because DataView doesn't have an inner element.

Ok, thanks. I searched for the wrong keywords I guess.

I added those fixes to my overrides file. That is getting quite long with bug fixes. When will there be a bug fix release?
