There is no need for a regression test, the result will be meaningless.

Main window disappearing from the task bar has beed caused by the patch
which marked owned windows as NET_WM_STATE_SKIP_TASKBAR. That has caused
a "regression" for apps developed in Delphi since they use a visible, but
zero sized (0x0) window as an owner for main app window. Wine didn't map
(make visible) zero sized windows because Window managers don't handle
them gracefully. Then I've sent a patch which maps zero sized windows
and fixes the previous "regression". Now the problem is that apparently
Window Managers disable minimize,maximize and size functions for zero-sized
windows, and that's what needs to be worked on/around now.
