Ctrl+Backspace inserts new item into unordered list with Firefox

[PatrickJosh]

Describe the bug Since the update to Nextcloud 29, pressing Ctrl+Backspace in an unordered list behaves weirdly. When pressing it with more than one word left in the current line/item, it behaves normally and deletes the word before the cursor. However, when pressing it with only one word left in the current line, it inserts a new item below and focusses this item. However, it only happens with Firefox, not with Chromium; there, it behaves normally. Have a look at the following video to get a better understanding:

https://github.com/nextcloud/text/assets/32456639/3c010557-5768-4067-8b5e-3ccc27e177ab

In the video, I only press Ctrl+Backspace, nothing else.

To Reproduce Steps to reproduce the behavior:

1. Have an unordered list
2. Press Ctrl+Backspace with only one item left in the line

Expected behavior The last remaining word is deleted as well.

Screenshots See video above.

I can reproduce this on latest Text main branch, but not in a Tiptap sandbox.

This has indeed been resolved by the library update. Closing.
