Add count for approved comments filter

[scribu]

On wp-admin/edit-comments.php, Approved is the only filter that doesn't have a count after it.

[scribu]

Current patch adds the count and updates it dynamically when (un)approving a comment.

However, it doesn't update it for all the other actions: replying, trashing, deleting, marking as spam.

I like this but I think we'll need to account for the other actions if we're to do it.

#17933 has an updated patch.

[scribu]

Sure, but it doesn't handle the JS part.

11200.2.diff​ adds the count and handles dynamic counts, of which there are many to account for. Still need to handle delete

[wonderboymusic]

In 33654:

Comments shouldn't have more than one _wp_trash_meta_status entry. When deleting _wp_trash_meta_status, also delete _wp_trash_meta_time.

See #11200.

In 33655:

Comments List Table:

• Show count next to "Approved"
• Properly increment/decrement counts when row actions are clicked
• In _wp_ajax_delete_comment_response(), return the comment's status with the supplemental data
• Handle counts properly on each scenario of undo

See #11200.

Comments List Table:

• Properly increment/decrement approved/pending bubbles in response column

See #11200.

In 33657:

Comments List Table:

• In a view that initially has comments, but they get removed due to user actions: show the No Items row instead of bombing out and showing nothing (which looks broken)
• To accomplish this, in WP_Comments_List_Table::display(): call ->display_rows_or_placeholder() instead of ->display()
• Listen for the end of row .fadeOut()s if necessary using jQuery Promises

Fixes #11200.

need to do a few more things here

[wonderboymusic]

In 33662:

Comment List Tables:

• Ensure that dynamic bubble counts are in sync by comment_post_ID
• Scope :animated to #the-comment-list

See #11200.

[wonderboymusic]

In 33663:

After [33662], remove unused var.

See #11200.

[wonderboymusic]

In 33692:

Comment List Tables:

• Toggle visibility of pending bubble when a comment is dynamically moderated
• Add a CSS class to the pending bubble to hide it / remove to show it

See #11200.
