Tbh not sure this should even be BAT. It's a corner-case in handling leaks
(or not), that doesn't feel like BAT material. Especially given that it
needs at least 1 modeset or two, so won't be fast.
We need to stop cramming everything into BAT simply because we don't have
any other CI. Because last time we've tried to run everything it also
didn't work ...
Also, BAT is over time, that pretty much means an embargo on new BAT
tests.
Thanks, Daniel
