    inspector: Make picking work again
    
    We used to either make the inspector see- and click-thru
    or lower it, but sadly translucency broke after we
    removed surface opacity, and lowering doesn't work
    on Wayland. So just hide the inspector window while
    we are picking.
    
    Fixes: #2528
