Comment thread leads to "404 Not Found" error page

+5
−0

This answer has one comment, $X\times X \cong X$. But when I attempt to click on the comment to show it, it leads to a 404 page.

Why is this?

(Update: the comment is not deleted as I had previously thought; it is accessible at https://math.codidact.com/comments/thread/11717 , and one can access it by Ctrl-clicking to open it in a new tab. The problem is that some JavaScript function in Codidact is returning "undefined" as the comment thread number and so the Codidact website makes an XHR request to https://math.codidact.com/comments/thread/undefined/content?inline=true&show_deleted_comments=0 ---the "undefined" there ought to be "11717".)

(Update 2: It seems to have something to do with math in the comment thread title---see the test comment I made to this post, titled $X × X$.)

Thanks for noticing these are the same issue. It's only thanks to you linking to that post that I now realise that one also has MathJax in the thread title.

@trichoplax Now that I think about it I'd assume the issue is that MathJax causes the comment link to be recreated and this does something to the interface between the JavaScript application code and the DOM, but my reading of the application code hasn't sufficed to figure much out…

Just knowing that MathJax is involved is a help for people looking into this.
