Can not insert text before Mention

[susnux]

Describe the bug
The cursor can not move before a mention, so if the first thing inside a document is a user mention, then you can not add anything before it.

To Reproduce
Steps to reproduce the behavior:

1. Open empty file
2. Add a mention
3. Try to add something in front of the mention

Expected behavior
Cursor can move before the mention.

Client details:

• OS: Linux
• Browser: Firefox
• Version: master
• Device: desktop

There's actually other objects with the same issues. Out of my head I think that tables at the beginning of the document have the same problem.

Seems like the problem only exists in Firefox. In Chromium, I can move the cursor in front of a user mention even if it's the first node inside the document. Also reproducible in the Tiptap example at https://tiptap.dev/api/nodes/mention

Likely it's because of the contenteditable: false attribute for the user bubble. When removing the attribute, I'm able to navigate in front of the user bubble. But certainly that's not what we want 😉

I opened ueberdosis/tiptap#3320 upstream.

I reported a bug against Firefox since this looks like a browser bug to me: https://bugzilla.mozilla.org/show_bug.cgi?id=1796943

I can confirm this Issue. A few details that i hope are helpful to you:

• This happens on chrome version 114.0.5735.106 on macos v 10.15.7
• collectives version 2.5.0, Nextcloud version 26.0.2
• It happens in the middle of the document as well: if you create multiple tables directly after each other, there is no way to get text between them.
• I see the cursor jump from in front of the table / behind the table into the first/last cell of the table. I attached screenshots, where i marked the behavior. Green is where the cursor should be, and where it is for a splitsecond. Red is where the cursor jumps to. This happens if you try to go get the cursor there by using the mouse or with the arrow keys.
