Weird bug with comments

Since the new update, all of the comments in my custom blocks have become closed and completely vertical (refer to picture):
I know it doesn't affect the custom HELP section in any way, but it's still a bug, so I thought I'd post it here.
Edit: Turns out it does affect the help sections (refer to picture):

That looks SO FUNNY!

Sorry, I have no idea how to help. You have tried dragging the thing at the bottom - Screenshot 2020-11-18 155115

Haven't you?

Yes, and clicking it reverts the comment to its original state, but when you're a custom block hoarder, its kind of annoying to have to do that over and over for each one

Can you share a project that shows this issue? I can't seem to reproduce it.

I think it’s one of those things that only happens once maybe and never again, unless someone has a project with custom blocks that have custom help screens and hasn’t fixed them yet. Still not sure if it happened for everyone though
