Had not run a proper run with `LockingMode == LM_LIGHTWEIGHT` as default since that commit. So found it when I sent of a run, and yes the C2 assert that checked this found it. 

GitHub actions has very limited non LM_LEGACY testing. Our LM_LIGHTWEIGHT teir3 testing would catch this. It had just not been ran since that commit.
