Deck comments not saved if last thing is a line break

Since about 2-3 weeks (version 1.11.? to 1.11.2) whenever I write comments in the web GUI and I finish my last input with a line feed, the data will not be stored!

To Reproduce
Steps to reproduce the behavior:

1. Go to deck, create a new card. See that after "Beschreibung" it will say "not saved".
   
   After waiting a few seconds the card update will be saved, both shown by the "not saved" disappearing and the "Last changed" will say something like a few moments ago.

2. Write some more and finish with a line break. Now you can wait forever and nothing will happen!
   

3. Open another card and go back to you initial card and you will see that everything you entered (when you used the line break at the end) is gone.
   

Expected behavior
Everything should be saved, no matter if I use a line break at the end of whatever I enter.

Maybe this has something to do with this issue:

Client details:

• OS: Windows
• Browser: chrome and firefox
• Version: nextcloud 27.1.4 with deck 1.11.2

Reproduce the issue in the Deck web GUI by creating a card and editing its comments or description with and without a trailing line break. Compare the save behavior and persistence after navigating away and back. Done means entries ending in a line break are saved and restored normally.
