Thank You

First thing first, fantastic idea to allow this GitHub behaviour in VS Code too (infact I thought it was odd vscode-github-markdown-preview wasn't allowing it yet (as I found out in your PR too).

Before having your extension running on my Code I had to write it with an extra empty line in order to avoid this mess

My Issue

Now that I have it installed, a minor problem arised (and I bet it's just for me)

Here is what bugs me: my friendly empty line now stops the rendering

Works fine without an empty line

My Suggestion

It might be useful to allows that empty line to still be rendered as in GitHub
e.g.:

Hello, I'm using your plugin and it seems pretty cool so far, but i had an issue:
Due to how your plugin works, the icon of the alerts always seems to be black and it doesn't really fit my page:

I wanted to ask if you could add a way to easily modify the icon's colors by maybe adding a config passable to the plugin via the use function of markdown-it (i think it's doable since you're using svgs)
A little example from matkdown-it-anchor in case you didn't get my explanation:

markdownIt({ html: true }).use(
    markdownItAnchor,
    {
      permalink: true,
      permalinkClass: 'anchor',
      permalinkSymbol: '#'
    }
  )

I also noticed that not all warnings from GitHub are present in your lib, github currently supports
