Rich Text Editing No Auto Save

Steps to reproduce

1. Enable notes rich text editing
2. Type something
3. Observe no auto save like traditional edit mode

Expected behaviour

Like in edit mode, the rich text edit mode should save a second or two after inactivity.

Actual behaviour

Rich Text editor mode has no auto save feature and requires manually saving each time

Logs

Log entry every time the edit tries to save:

Log says no permission to that php file. There is access to that file. Globally. And all directories above it.

Start by tracing the rich-text save flow from PUT /apps/text/session/.../create through apps/text/lib/Service/ApiService.php, SessionController.php, and DocumentService.php, comparing it with traditional edit mode. Reproduce the two-second inactivity case and the reported permission error; done means rich-text edits save automatically without requiring manual saves.
