Bug: If you add a table on a list it adds it above the list and results in invalid exported HTML

[osc245]

If you add an unordered list and then on the list add a table it will add it above the list item and the exported HTML will contain an empty unordered list tag which is invalid HTML.

Lexical version: 0.17.1

Steps To Reproduce

1. Add unordered list
2. Click on the top list element
3. Add a table
4. Observe the table is above the list element and if you call the $generateHtmlFromNodes function it will contain an empty <ul> tag

Link to code example:

I noticed this in my own app using the INSERT_TABLE_COMMAND command but was able to reproduce it in the Lexical playground so I thought it was easier if I just demoed it using that.

The current behavior

Table gets added above the list item and exported HTML contains an empty <ul> tag

The expected behavior

Table gets added below the list item and exported HTML does not contain a empty <ul> tag

Impact of fix

• This bug seems somewhat but not catastrophically bad. To get around it I need to strip out these empty list elements after exporting the editor content
• This happens consistently for me, both in my own app and in the Lexical playground. I've just mentioned unordered lists for simplicity but it also applies to ordered lists
• This seems like a bit of an edge case but as it is general behaviour I think it could benefit lots of users
