List item (asterisk) is added to the last line

Please use GitHub reactions 👍 to show that you are affected by the same issue. Please don't comment if you have no relevant information to add!

Describe the bug
Opening a note containing a list (both ordered and unordered) followed by an empty line automatically adds a list item in place of the last line. If the item isn't manually removed, then it stays as part of the note.

To Reproduce
Steps to reproduce the behavior:

1. Make a following note via the web UI or otherwise (must include an EOL before EOF):

* foo
* bar

2. Open the note on Android (Plain edit)
3. Modify foo to foofoo
4. The note now contains an extra list item which (added one the note has been opened on Android):

* foofoo
* bar
* 

Expected behavior
The automatically-added list item should not be part of the note. I.e. not included in the text unless user actually adds some text to it.

Stacktrace N/A

Start by reproducing the issue in the Android app's Plain edit mode using the supplied note content and steps. Trace how a trailing empty list line is handled when the note is opened and edited; done means the temporary empty list item is not persisted unless the user adds text.
