Help - Zoom Bar does not work in "Bottom Start" custom ROMs

[sudermatt]

I prefer the "Start on the Bottom" 6.5.1 ROMs with Manila 2.5.

I have not found on where the Zoom Bar actually works as a zoom.
In just about all of them, the zoom bar acts like an extension of the screen.

I've posted in the ROM threads but can't seem to find an answer.
I'm sure this is a known issue...

Since this seems to cross ROMs, I thought I would post out here and see if there is a FIX I can use...that way I can use the the rom I like best.

OR...anyone found a "Bottom Start" M2.5 rom where the zoom bar actually zooms?

Thanks,
