ST build 3019
List items in Markdown only appear to have the punctuation scope defined for the first item in a list.
e.g.
# Title
- unordered list item
- another list item
- subitem
1. numbered list item
2. another one

I would expect all the - and . characters to be highlighted in this example.
scope at the first - is: text.html.markdown markup.list.unnumbered.markdown punctuation.definition.list_item.markdown
scope at the second - is: text.html.markdown markup.list.unnumbered.markdown meta.paragraph.list.markdown
ideally, some syntax tests would be created as part of this package.
This has been fixed by some external packages like my PlainNotes or MarkdownEditing but the built-in Markdown package still has a lot of issues that has not yet been addressed.
I personally hope, markdown syntax gets some love in the near future.
@aziz If you can create issues for the problems you know of, and include example content, I will work on getting it fixed up!
