Can you give me an example of which specific user/feedback it happened to? I can't reproduce this issue and there isn't anything in the code that would do this, as far as I know. It literally copies the text that you see on the feedback page.
I don't understand why only reference link would be messed up.
It happened two times (that I know) and you can find more information in this topic:
https://bitcointalksearch.org/topic/nvk-c0inkite-c0ldacrd-is-anti-opensource-nutcase-5519534Have you installed any other extensions recently? If there are any other extensions, you could try disabling them all except BPIP and see if the issue remains.
I am in process of doing that after talking with PowerGlove in private.
Only two other extensions installed in my browser is uBlock orign, but that is fully disabled in bitcointalk forum.
Second extension is Violentmonkey for userscript, and I was using Ignore threads script by NLNicoo.
EDIT:
Sorry guys, I did some testing and I identified the culprit, it was Ignore threads user script from NLNico.
I was able to reproduce the bug, and no wonder when we know this was released back in 2016.

interesting that I tried the same userscript with Greasemonkey extensions, and there was no issue (so far).
