What do you mean precisely by adding a link to that bug in Kicad 6?
There are now over 18000 closed issues on gitlab. So you can add a link to that old issue and add it to #18945 so people who are familiar with the KiCad source code can have a look of whether that old topic (and it’s comitted fix) is relevant to this new topic.
Thumb up. ------------------------
Thumb up on the linked gitlab page, not here.
This is almost certainly not the V6 bug as I did not find it trying V7.
We are talking about version 8, not 7 nor 6.
