Subject: [PATCH] Add Qt:WindowStaysOnTopHint to resource preview Closes #2971

Qt on Ubuntu 23.04 includes https://github.com/qt/qtbase/commit/f9e4402ffe, which during show() under certain scenarios (for example Qt::ToolTip windows) would destroy and recreate the xcb window.

Adding Qt:WindowStaysOnTopHint to the window flags for ToolTip windows prevents the xcb window from being destroyed and recreated during show().
