In certain cases, the link 'add / show # more comments' under a review doesn't work. I can reliably reproduce this when doing the following:
- Open a review you have already done (or one that is completed). (You can use this review or this review as example).
- Click the 'add / show # more comment' link. This should show the comments.
- Click next
- Click the back button in the browser
- Try to click 'add / show # more comment' again.
This doesn't work. Inspecting the network tab in the developer tools shows that on clicking this link, 3 requests are made to the same page, all returning with 200 OK and all the comments in them. I am suspecting that somehow three click handlers are attached to the link, who all fail to properly update the comment section.
I originally had this bug when reviewing such an entry and clicking back. That's not really great to reproduce the problem though. I think step 2 and 3 can be swapped and the outcome would still be the same, but I couldn't test that just now. I had this bug in the 'close review queue', but I suspect this is the same for other queues as well.
Edit: A similar issue seems to happen with the review buttons. I don't see this as a duplicate of that question, because there are functions on the page that will still work (such as clicking the next button, or clicking this exact same link without doing step 2).
