Copying a comment makes material unsavable

I found this bug when i copied a comment bubble from a material function to a material.

Basically, if you have a material function hooked into a material, and you copy a comment bubble from that material function into the material, the material becomes unsaveable.

I attached instructions for how to replicate this in a blank project

.

This happens on 4.12 and 4.13 preview 3. I didn’t try another version.
