Checkboxes don't get checked in rendered mode / Same Issue as #2061 again

Describe the bug In rendered markdown view, checkboxes can be checked but after closing the card this will be lost. The next time you view the card, the checkbox will be unchecked again. This only happens when viewing through a browser, the mobile app (for Android) behaves as expected. I think issues #2061 was about the same bug, but it was closed and should be resolved with a release in late 2023.

To Reproduce Steps to reproduce the behavior:

Open a deck card
Enter Markdown in the description, eg. "- [ ] buy apples"
Change to rendered markdown view
Check the Checkbox
Close the card
Task reading on the card will be "0/1" (Bug, should be "1/1")
Open the card again
Checkbox apears unchecked (Status should be "checked")

Expected behavior When i click a checkbox in rendered view, this should be saved when I close the card

Are you using an external user-backend, if yes which one: LDAP/ActiveDirectory/Webdav/...

Nope.

I did not find any log entries related to the deck app at al. Other logdata contains usernames and other personal data. I can share this via mail if really necessary.
