[3.x] LockingGridView doesn't scroll when using mouse scroll wheel in the locked sect
Minor bug/feature request:
1. Open Ext examples, locking grid example
2. hover over locking part, scroll down on mouse wheel button. Somewhat inconsistent that it doesn't scroll...
That's been reported several times.
I see two ways to solve this:
1. Track the mousewheel event on the locked section and scroll based on the delta value. The problem with this is that the scroll speeds of the locked and unlocked sections are probably going to be different.
2. Make the locked section overflow:auto and somehow hide the scrollbar. But IIRC there are some problems with old browsers (FF2?) that always show scrollbars on top.
