It is not priority issue at all (as I work around by copy/paste back and forth from my EmEditor, now).
I think the integrated editor used to respect my code style by inserting tabulations (as the rest of my script) when pressing ENTER to append a new empty row.
Now it has been inserting new rows with heading spaces instead of tabulations, creating some inconsistencies that I have to remember to fix before committing my changes to my user scripts git repository.
I don’t know if it used to guess what to insert (spaces or tabulations) or if it used to always insert tabulations. Or if I was dreaming. Maybe it always has inserted spaces and I work arounded that all the time, I don’t know.
