When you want Live Preview to allow clickable image links.
Proposed solution
Currently in Preview mode you can use the syntax [![[image.png]]](https://site.com) to allow an embedded image to be clicked and open up the corresponding website. However, in Live Preview Mode, it currently does not work. That would be quite cool if it did.
I hope this doesn’t muddy the waters of what I am getting at. I don’t think it will. Also, I totally understand that this is likely not recommended usage that I am showing here.
