That actually makes some kind of sense, since this bug has something to do with garbage collection, and THP may result in different memory allocation patterns due to the changed page size. Except.. Isn't THP enabled by default on most systems?
Indeed it appears you're right, it defaults to on nowadays. Didn't used to (e.g., checked and it's not enabled by default in Stretch).
Also, I left the VM repeatedly starting and stopping the assistant overnight; that one failure I got was the only one it saw. Out of many thousand attempts. (And unfortunately, "power cycling" the VM didn't produce another, so it wasn't just the first run).
So back to the drawing board, I guess ☹
