Only manually expose the wasm window on raise/lower if it is visible

Browse Source 
If the window is manually exposed and the window is invisible, the result
is blocking the visual sync and repainting of the window, which makes
the window 'dead' from user perspective until they click/activate it,
which again sends an expose event to the window, restoring its updates.

Fixes: QTBUG-105363
