Code disappearing when editor opens

[Waldorf-Techie]

When I open a file for the first time, I sometimes see that lines of code have been randomly erased. CTRL-Z does not revert this, so it is not something caused by any user interaction with the program. The line numbers show that something used to be there, and the erasures don't line up neatly with lines--for example, the end of line 7, all of lines 8-19, and the beginning of line 20 were deleted in one program.

This has happened enough times that it seems to be a systemic error. This never happened to me with the Glowscript editor. It is very frustrating, as there is no backup (as far as I know), so I have no way to restore the programs affected.

Example program where this has happened:
https://flaskdstorehost-dhppn6xgeq-uc.a.run.app/#/user/HG_NY/folder/FileWork/program/AddressBook/edit

I don't suppose you have any version history on your end to check when the change happened?

Wow. Sorry about this. I have not experienced that. Maybe make copies of code before you test with the new editor.

I'll try to look for a source of this problem.

Can you share details of Browser, OS, etc.?

Windows 11 Firefox The problem seems to usually arise within indented code blocks, but this may be coincidence.

If you see any way to prepare a document to make the behavior reproducible, that would be helpful.

Another useful bit of information would be any output that might appear in the javascript console.
