    floating-bar: Stop overriding widget measurement vfunc
    
    We are doing it in order to account for the border and padding.
    
    That's unnecessary, as GTK already accounts for border and padding
    from CSS. Actually, duplicating this work has been just adding more
    padding, resulting in a despropotionate padding at the start side.
    
    Remove the unnecessary overrides and just add 2 pixels more padding
    to preserve the visual height.
