Azure DevOps PR decoration undocumented behavior?

I’m not aware of such limit. Maybe @Julien_HENRY can give more insights.

When you say “when we set the status in the PR to WontFix”, you mean when you do it in Azure DevOps UI?

I guess the idea is to not “pollute” too much the PR with useless comments (when issues are fixed, there’s no more problem). You would expect the comment to be set to “Closed”?
