Spacing & numbering issues with nested lists

[dmorrison-olive]

Describe the bug

I see a couple issues with nested lists.

One issue is that there are extra line breaks between list items in nested lists. When I render this in my application, it wraps text with a <p> if there's an extra line break (which has implications for margin/padding).

Another (small) issue I see is that numbering gets off for numbered lists. I realize this doesn't matter with Markdown, but I thought I'd note it.

Additional context

I see this with the latest version (1.3.0). I'm using no plugins.

Thanks for the utility!

@dmorrison-olive thanks for reporting this 🙏

extra line breaks

Sorry that it takes so long. I'm working on it but haven't found a good solution... It's really tricky to fix 🤯

numbering gets off

Unfortunately, that's not that easy to fix, since I'm already allocating the numbers before it's detecting that an item is empty and can be skipped. Since it's just visuals, I won't fix it right now.

Thanks! And that makes sense about the numbering, since it doesn't matter and is technically still valid Markdown. 👍
