JJ2+ 5.4 (2016-12-07) applied to JJ2 1.23, no TSF, in Wine.

Start singleplayer with Jazz on Medium, beat the queen. Before the level fades out, bounce on the leftmost red spring, face left. Wait for the gem-counting screen, this makes you stand inside the spring. After the score counter, the screen turns black.

Expected: Jazz runs off the black screen, then the next level loads.

Observed: Next level loads without any run-off animation in between.
