Cursor jumping and no space in panel kirby blocks list

Hello everyone,

I’ve got a weird bug (?), so far, everything works fine in panel, I have a blueprint field for blocks, but somehow I can’t write sentences when the list is added. The cursor jumps every time after one keystroke to the last position of that block when I’m trying to type something.

I made a small screencast about it:

Anyone has an idea what the issue may be?

What does your blueprint look like?

Hm, just tested this in a 3.5.3.1 Starterkit and cannot reproduce the issue. Could you please also test your blueprint in a fresh Starterkit?

If that works, what plugins are you using that might interfere?

For the record, removing plugins from original instance didn’t helped. I ve created a new kirby instance from scratch, transfered data from previous one and now everything works like intended.
