Typing in long md files is slow (~1s delay)

This issue respects the following points:

• I have read the FAQ
• I have searched for existing issues
• The issue affects the Notes Android app, neither the Notes server app nor the Nextcloud Android app.

Describe the bug

First of all, sorry in advance if this issue is "wrong" here. I did a check and this affects the Markdown web editor and the editor in the Notes server app aswell. Do with it as you please.

Got a couple of very long notes files. 5000 lines or more... (please don't judge).

• 5000 lines or more in one note markdown file
• App is in Markdown code view
• Typing anywhere in the file with the android keyboard

Typing in them has like a one second delay on each keystroke. I'm no expert but is there some very inefficient processing going on? Like, is it going through the entire file each time you change something? Because this delay is cumulative. 5 keystrokes = roughly 5 times the time. I have tested a couple of different markdown editors and while this very issue is certainly not unique, there are other apps that behave normally, which is no delay at all.

If you think this kind of delay is normal or acceptable, I don't know what to tell you. It's a plain text file and there are ways to deal with syntax highlighting efficiently. All that being said, I appreciate developers efforts here, all in all the app works great and gets the job done.

Reproduce the delay in the Android app's Markdown code view with a note of 5,000 or more lines while typing with the Android keyboard. Start by tracing the code-view editing path and measuring work triggered on each keystroke. Done means typing is responsive for long Markdown notes without the reported cumulative delay.
