[TxMt] Find Window visible in all mission control spaces

I’ve noticed that the find window is not tied to the same application space as the rest of the Textmate windows. Its shown globally as if the window were assigned to “All Desktops”. This is quite annoying as I often will switch applications using command tab, and then switch back to Textmate via the same key. When i return to textmate, the find window shows up in the wrong space, while the editor windows remain in their correct space.

The desired behavior would be for the find window to occupy the same space as Textmate, and upon switching to the Textmate application, the corresponding desktop space should be automatically selected.
