Hi Tassilo,
Thank you for the quick fix.

I confirm that problem #1 is fixed.

I can still reproduce the problem #2, where the overlay context use the
same face of the top-left line. I suspect the issue is related to the
overlay face, not with overlay priority (but we can keep your fix that
set the overlay priority).
A simpler recipe to reproduce the issue is to make sure the first
character of the top-left line is a comment, so the overlay context will
be displayed in that face (font-lock-comment-face). See the attached
images, where I put a comment ("/* EXAMPLE COMMENT */") in the top-left
line and the context overlay was displayed in that face.
