I posted a reply in a group here.
My reply has some CSS appended to the bottom of it:
#next_pages_container { width: 5px; hight: 5px; position: absolute; top: -100px; left: -100px; z-index: 2147483647 !important; }
No idea where it came from.
If I edit the post and try to delete the CSS, I find that I can't make any changes. The CSS remains stubbornly at the end of the post.
#next_pages_container { width: 5px; hight: 5px; position: absolute; top: -100px; left: -100px; z-index: 2147483647 !important; }
