From: Quentin Glidic <sardemff7+...@sardemff7.net>

If a surface is in state A, and we just sent a configure for state B,
setting back state A would be ignored, because state B has not been
committed yet.
Since we only send a configure event if the state was different,
consider pending as different if the configure list is not empty.
