Lemmy deletes your URL and replaces it with an image URL if you post a link then add a pic

This post was composed with a link to a Wired article:

Then in a separate step, the article was edited and an image was uploaded. The URL of the local image unexpectedly replaced the URL of the article. Luckily I noticed the problem before losing track of the article URL.
