New changes to the block code are no longer taken into account


I have a problem with the code editor block. For a long time now.
When I modify the contents of the block for dozens of minutes at a time, after a while the new corrections I make to the code are no longer taken into account.

However, they are still displayed in the code bloc.

It’s only when I refresh the studio’s web page that I realize that the last few modifications are no longer saved.

It’s a bit hard to explain, but imagine that from the second screen onwards, my updates continue to be added and displayed in the editor, but are not applied.

And if I refresh the page, I end up with the second screen (all modifications between screen 2 and 3 have disappeared).
