Screenshot of a test case which toggles windowed fullscreen several times, then the window commits in response to each, and we verify the state in between.

   After trying a few approaches, I ended up doing it "properly" by associating the (entirely compositor-side) windowed fullscreen state to window configures and commits. This lets niri correctly track if a given fullscreen window commit was real fullscreen (so e.g. we need to draw a black backdrop), or if it was windowed fullscreen.

   This even works across a chain of toggling windowed fullscreen, then the window slowly acking and committing them, and I have a test to verify that.
