NC25: Tab key shortcut broken - NO possibility increase list intentional level anymore

[Pilzinsel64]

Describe the bug

• Since Nextcloud 25 it is not possible anymore to increase the intentional level of a list entry. Traditionally it gets done via the TAB key but since NC25 this TAB key points to the close button.
• There is no other option to increase the list intentional level
• The only workaround: Download the file, enter the TAB in the raw text file, upload the file again and continue work. This can be annoying when doing slightly bigger lists.

(Not sure if this bug should be addresses to the viewer app instead, as some people mentoined the TAB key still works in Collective Apps that uses text.)

To Reproduce
Steps to reproduce the behavior:

1. Open a (new) text file
2. Start a new list and write the first entry
3. Press enter to start the second point
4. Now press TAB on keyboard to increase the list intentional level because we want to add a sub-entry to the collection

Expected behavior
The intentional level of the second entry should get increased by one, like this (As of Nextcloud 24.0.7):

Screenshots
Instead the close button get focused.

Another important notice:

• This happens only if there is NO headline in the document. It doesn't matter where that headline is, as soon as at least one headline is there, the TAB key works again.

I'm having the same issue and can confirm the workaround.

@Pilzinsel64 you are a genius, thank you!

This bug only occurs when Text is loaded in the Viewer. In Collectives or a single file public share, it doesn't occur.

And even if loaded in Viewer, the tab key to increase list indention works if any of the following node types exist in the document:

• heading
• link (with link preview widget)
• table

In a document with just a heading and a list, key tab indention stops working when commenting out addNodeView(). And indeed, all three node extensions result in a VueNodeView being loaded. But on the other hand, many other node extensions (like mentions, image, callout) don't result in tab indention working. So for now I'm a bit clueless 🤔

Another noticable difference: when logging the keydown and keyup events in Firefox Debugger, the parent element is div.ProseMirror in documents where tab indention doesn't work, but div.ProseMirror.ProseMirror-focused in documents where it works.

This is still an issue and needs further debugging.
