False Positive Posting Error: "Invalid HTML was found in the message body"

When trying to post to PowerBI Desktop, I get a confusing invalid HTML error asking me to correct highlighted text, but theres no highlighted text - theres no text at all. See my screenshots.

I created the post using only the native Fabric post toolbar options, so there is nothing to suggest I truly added incorrect HTML.

This has happened numerous times with other posts. This recurrent error creates a dissapointing amount of friction when interfacing with the fabric community.

It will probably work fine if I try posting later. I'm only making this post to raise awareness of this recurring issue in the fabric platform.
