    window: Ignore resize if fullscreen
    
    The terminal update size function will not change the window size if
    maximized or tiled, but does not account for fullscreen window.
    
    As a result, if the terminal window is fullscreen, the size is updated
    which cause the window to shrink because of size increments.
    
    Make sure `terminal_window_update_size()` accounts for fullscreen state
    as well and return early in that case.
