Backspace on parent items in nested lists does not work

What’s the bug you are facing?

TipTap/Prosemirror behaves a bit UX-unfriendly out of the box when one attempts to delete foo or bar alone in a nested bullet structure like

• foo
  • bar
    • baz

How can we reproduce the bug on our side?

• Go to https://tiptap.dev/ or https://prosemirror.net/
• create the above nested structure
• set the cursor at the beginning of bar and press backspace. foo disappears, but nothing else happens

Can you provide a CodeSandbox?

No response

What did you expect to happen?

Lines joining, e.g. behavior similar to https://h9xxi.csb.app/, https://remirror.io/, or https://app.bangle.io/

Anything to add? (optional)

I’ll look into that! Moved this ticket into the 2.0.0 Milestone too as I think the editor behavior should be fixed when we go stable.

@YousefED you mind if we look into your solution for this issue?

I’m sure it’s fine…
