The first comment shows only when page is refreshed

Subj. Tested on a fresh Backdrop setup. The first comment (or multiple) never show unless you refresh the respective page. After the refresh everything works as expected.

So the first test comment in the below screenshot did not show up until the page was refreshed. Comments 2 and 3 showed as expected without page refresh.

The https://docs.backdropcms.org/api/backdrop/core%21modules%21comment%21comment.theme.inc/1 lists only three functions available:

template_preprocess_comment	Preprocesses variables for comment.tpl.php.
theme_comment_block	Returns HTML for a list of recent comments.
theme_comment_post_forbidden	Returns HTML for a "you can't post comments" notice.

template_preprocess_comment Preprocesses variables for comment.tpl.php.
theme_comment_block Returns HTML for a list of recent comments.
theme_comment_post_forbidden Returns HTML for a "you can't post comments" notice.

So apparently the template_preprocess_comment_wrapper() of Drupal 7 was dropped on Backdrop, therefore the ajax_comments_preprocess_comment_wrapper(&$variables) never kicks in.

After reading https://docs.backdropcms.org/change-records/new-layout-module-implements-a-drag-drop-model-for-building-layouts I came to conclusion that the least intrusive way to address this issue would be implementing the hook_preprocess_page() not to deal with layouts, because websites can change their layout templates and the solution needed to be universal.

@alanmels I never got back to this project and haven't needed it on a client project recently, but I was investigating the same issue over here, I think:

• Remove template_preprocess_comment_wrapper #7

I don't know that I found anything that you haven't already discovered. Feel free to close that other issue and rough work-in-progress PR as you see fit.
