My guess (without looking) will be that this is connected to the complex issue of representation of an array of nodes in the editor. I think this issue - #62916 - references the most relevant pieces (other issues/past PRs). If that is the case then topic:editor tag is important and currently is missing. Makes sense to ping @KoBeWi as he did fix connected issue twice.
