External editor regression

Joplin 1.0.218 (prod, darwin)
MacOSX Catalina (current)

emacs is my external editor. since the upgrade yesterday, when i C-x C-s save in emacs, the note in joplin is not updated. it used to be.

if i turn debugging on, per instructions, it works!

if i command-s save the file in the app, from them on external edit seems to affect the file.
