[user32]
- When themes are active and the text of a window changes, we should send the
WM_NCUAHDRAWCAPTION message instead of drawing the window directly ( which will result
painting a classic caption on the themed window)
- Fixes explorer window that is repainted with a classic style when a subfolder is opened
