The issue is also present in Mozilla Firefox 132.0 with Emacs.

A very stupid fix is to comment out the listener which waits for the gt:kill event from the codeMirror6 function.

I'm not sure what that part of the code is meant to do, but removing it lets you edit the cell multiple times without having to refresh the window.

Code change here: https://github.com/atodoron/GhostText/tree/CM6Errors for someone more familiar with the code base.

I looked into the code. The fields are initialized once by calling function listener(field). This installs the two-way listeners for each field. The codeMirror6() initializer function though is set up in a way to ever be run once, because gt:kill aborts the AbortController and that removes all the listeners.

Now I don't remember why I decided to add gt:kill only to this field, but to fix the issue it would have to either be removed entirely or adjusted so it can be "restarted" somehow.

I think I'd have to re-architect the whole extension again to properly fix this, but for now maybe just removing gt:kill should work.

@atodoron maybe you can try

I don't know if it's right, but the first commit which gets rid of the 'gt:kill' listener completely is working well enough for me to stop using my work around macro in jupyter notebooks. 🙇 thank you.
