I’ve only noticed it recently, so perhaps it’s only since installing WordPress 6.3, but the “hover over” bits on page thumbnails are showing the text ITEMPROP=”DISCUSSIONURL just before “Leave a comment”.
If you look here, for example:
https://lofi-gaming.org.uk/diary/
Hover over the post image, and the dark grey slide-in bit comes up and shows you.
Seems to be that this code is broken:
<span class=”comments-link”><i class=”icon-comments icon-metas” title=”Comments”></i> itemprop=”discussionURL”Leave a comment</span>
