I've edited that code just recently so would want to work on this

[est31]

Made PR #50829 to fix this

[vegard]

@est31 Thanks for fixing this :-) I also reported a couple of other looping-related bugs in #50576 in case you also want to have a look at those.

@vegard wow those are quite nice bugs :p. Will have a look.
