Weird text editing behavior since latest update

Steps to reproduce

1. Open a text file
2. go anywhere in the text and press enter
3. the cursor jumps to the beginning of the file

Expected behaviour

pressing enter should just go to the next line

Actual behaviour

the cursor jumps to the beginning of the file.

Moreover, somehow, because I didn't care enough after pressing enter, the content of my file got deleted, and this empty file got automaticaly saved.

Again, for some reason, no versions of this file dating from less than 6 months are to be found in the web interface.

So, my file's content is definitively lost (well, I'll try to get it back from the backup)

Screenshots

Here's a screenshot of my file in the web interface:

Environment data

iOS version: e.g. iOS 14.6

Nextcloud iOS app version: Nextcloud Liquid for iOS 4.0.1.1

Server operating system: Debian/stable

Web server: Apache

Database: Mysql

PHP version: 7.3

Nextcloud version: 22.0.0 RC1

Start by reproducing the Enter-key behavior in the Nextcloud Liquid for iOS app version 4.0.1.1 against the listed Nextcloud 22.0.0 RC1 environment. Trace the text editor's cursor movement, autosave, and version-history behavior; done means Enter moves to the next line without deleting or automatically saving the file.
