Premising that very probably a fix there would not 100% resolve that upstream issue but surely this deserves a fix :D

avivey edited projects, added PHP 8 support; removed Remarkup, Phorge.May 9 2023, 10:35
aklapper removed a project: PHP 8 support.May 9 2023, 13:37

This is unrelated to PHP8. This might turn out to be a duplicate/variation of T15372.

valerio.bozzolan added a project: Remarkup.EditedMay 9 2023, 14:09

(Sorry for the ping poing, re-adding Remarkup hoping to be useful since this seems an issue in Remarkup itself, but last word to avivey)
