Image Block: hyperlinks added to Image blocks without http(s) prefix append to page/page slug

1. Create new post or page
2. Add an image block, and insert an image
3. Add link to image block, using a URL without http:// or https://.

What happened instead
The URL entered appends to the end of the post/page slug:

Image Link:

Clicking on the image results in a 404

This was first reported on a WordPress.com simple site but we were able to reproduce it on a local WordPress.org, with and without the Gutenberg plugin (Version 10.3.1).

I suspected there was probably already an open issue and I looked up but I was not able to find it. Thank you @skorasaurus!
