When looking for a example-case, mistakenly did run 
jit-lock--run-functions, which requires args, Should run 
jit-lock-fontify-now - which might be evaluated in scratch - but doesn't 
help for the original issue.

While file a new report maybe.
Please close this, sorry for the noise and thanks for your care,
