Unfortunately it's not true. If tooltip is created without WS_POPUP
style weird things start to happen. I've just made several
Everything is fine only if virtual desktop is used.
If windows are managed by WM, then
- in KDE when tooltip is shown it steals focus from application,
tooltip window has WM border, titlebar and appears in taskbar;
- in GNOME tooltip steals focus, and has WM border
This is surely incorrect and even there exists opened bug in bugzilla
#2891. It likely has to do with window hints or something inside
window management code.
This should of course be fixed.

But also I think we should change tooltip control creation in our code
(there are 5 total places, all inside comctl32 code), as it will fix
this at least for wine common controls and it is what native does
(with native comctl32 this problem doesn't appear).
