Ignore/Unignore button has a mind of its own

I will post to a thread and it doesn’t appear on the talk page. Have I inadvertently hit the. Ignore button? Well, go find it in the Ignored folder. Can’t Unignore it from the bottom of the thread. About 50% of the time, using the plus sign on the right column in the folder works. If it doesn’t correct, have to Star the topic to bring it back into my Talk feed.

This has been a minor irritant for a couple of days.

Confirmed the + (Unignore topic) button is failing, somewhat.

To reproduce:
1. Go to https://www.librarything.com/talk
2. Pick a topic to ignore and click the "x" (ignore this topic) button. Topic disappears under the "Ignored Topics" sub-page.
3. From the left-hand menu, click to view "Ignored Topics" sub-page.
4. For the topic you just ignored, click the "+" (unignore this topic) button.

Half-Bug: Nothing appears to happen visually. The thread is not removed from your Ignored Topics. BUT, if you refresh the page, the topics you unignored are back in Talk again. (Removed from Ignored Topics)

NB: I think this may be related to our recent "onclick" changes here: https://www.librarything.com/topic/335252#unread ?

This was fixed under another bug report.
