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

Final singleplayer level as Jazz on Medium. Have TNT. Have Devan at the left edge of the screen, spread out TNT under the left island. There is a chance that Devan gets knocked out of bounds by the TNT explosion. You can still hit him with electro-blasters. Once you run out of electro-blasters, the stage is softlocked.

Expected: Devan should stay within the arena at all times? At least no softlock.

I'm not sure what vanilla does. WolfyJawa believes that he got something similar like this once in vanilla, but he's not sure what exactly it was, or whether it was a problem.

Issue again on livestream vod: https://www.twitch.tv/videos/134521175?t=34m15s I manage to hit Devan with the electro-blaster.
