Posting comments in deeply nested threads hangs

[zorbathut]

From cjet79:

When posting a comment in a deeply nested thread. (deep enough that any subsequent comments will be minimized. I think 9 comments deep.) When clicking "comment" the page will hang.

There is also a javascript error that gets thrown in the console:
Uncaught TypeError: comments is null
onload https://www.themotte.org/assets/js/comments_v.js?v=a90eb7d7:293
post_comment https://www.themotte.org/assets/js/comments_v.js?v=a90eb7d7:280
onclick https://www.themotte.org/post/508/culture-war-roundup-for-the-week/103865?context=8#context:1
comments_v.js:293:4
onload https://www.themotte.org/assets/js/comments_v.js?v=a90eb7d7:293
(Async: EventHandlerNonNull)
post_comment https://www.themotte.org/assets/js/comments_v.js?v=a90eb7d7:280
onclick https://www.themotte.org/post/508/culture-war-roundup-for-the-week/103865?context=8#context:1

refreshing the page will show that the comment was successfully posted

My best guess is that is an async error, and the page is trying to load the "more comments" button before the comment has been fully saved and retrieved from the server

can reproduce, might be related to ?context???

it's worth noting the comment does actually get posted, it just doesn't get inserted into the tree.

it looks like there simply isn't a replies-of-<id> div anywhere in there.

compare a different leaf which does have the div, even if empty

Seems to still be happening.

There are two code paths involved here. This PR only changed the rendering for shoah’d comments (where it ironically doesn’t matter). Needless to say, someone should rewrite that template so that there aren’t two largely identical paths.

Aha! That makes sense. Many thanks for doing the legwork on this, I'll get it live soon :)

Should now be live!
