Topic on Help talk:VisualEditor/User guide/Flow

I'm using a site running MediaWiki 1.35.13 and VisualEditor 0.1.2, and we've noticed that HTML comments which are inserted either by the Visual Editor or in wiki code with <!-- TEXT --> get deleted from the page if we use the visual editor. We plan to upgrade, but am not sure if the but is fixed in the latest version of VisualEditor compatible with the latest LTS version of MediaWiki, or if we would need to upgrade to an even older version.

Can anyone help inform us when this comment bug was fixed so that we know what minimum software versions we need to upgrade to? Thank you!

As far as I'm aware of VisualEditor was never supposed to delete comments. I tried to search for related bug reports but couldn't find much, maybe except for this one. Impossible to tell if this related without knowing more about the circumstances. I think it's easier of you update to the next LTS first and see if you can still reproduce the issue.
