Good morning Frans,

As a cross check I reverted the revert here and tried to reproduce the
problem again. It is a lot harder to trigger for me now (I was not able
to reproduce it yet). I did update my local git tree though, can you
reproduce this problem on your side with current git?

Kind regards,
Michael
