List: Deleting an empty item at the top of a (malformed) list reshuffles the block

[jasmussen]

This one is hard to describe, so it's best to test. Here's testing content:

<!-- wp:list -->
<ul><!-- wp:list-item -->
<li>Item<!-- wp:list -->
<ul><!-- wp:list-item -->
<li></li>
<!-- /wp:list-item --></ul>
<!-- /wp:list -->

<!-- wp:list -->
<ul><!-- wp:list-item -->
<li>Item</li>
<!-- /wp:list-item -->

<!-- wp:list-item -->
<li>Item</li>
<!-- /wp:list-item -->

<!-- wp:list-item -->
<li>Item</li>
<!-- /wp:list-item --></ul>
<!-- /wp:list --></li>
<!-- /wp:list-item -->

<!-- wp:list-item -->
<li>Item 2<!-- wp:list -->
<ul><!-- wp:list-item -->
<li>Item</li>
<!-- /wp:list-item -->

<!-- wp:list-item -->
<li>Item</li>
<!-- /wp:list-item --></ul>
<!-- /wp:list --></li>
<!-- /wp:list-item --></ul>
<!-- /wp:list -->

This will create two list items in a list, each item with further nested list items.

Notably the first nested list item of the first list item is empty. If you set focus on that block and press "backspace", suddenly you are focused in a new empty top level list item, as item 2. Expectation would be the list item was simply deleted.

@ellatrix do you know what this might be?

Confirmed this one in testing with both WP 6.3.2 and 6.4RC3 - definitely an odd one.

@jasmussen That's because the list is malformed. In the list view you can see that the first list item contains two lists instead of just one. Instead of fixing the symptoms, it would be good to figure out how you ended up with this state. How did you create this list, step by step?

I got to this state by copying from Google Docs. I find this happens somewhat often, I usually take notes in a list form similar to the above, and when copying over those lists this happens. Feel free to DM me and I can send you the specific Google Doc I used to copy over.
