Nested list item becomes single paragraph when indenting >=4 spaces #523
Description
Subject of the issue
It seems like if the 4-space indented list item is followed by an unindented text block, the parser would recognize all 3 lines into a single paragraph within the first list item. This doesn't seem to happen without an unindented text block after, nor with 2 or 3 spaces of indentation. With CommonMark, it seems that this behavior only happens when indenting >=6 spaces.
Your environment
- OS: Windows 10
- Packages: remark-parse 8.0.3
- Env: Chrome 84.0.4147.125
Steps to reproduce
Sample: (notice there are exactly 4 spaces in the second list item, the same happens with a tab character)
- Test

Test
remark
CommonMark dingus
Observation
Interestingly, when the indentation is done with 2 or 3 spaces, the parser correctly recognize the list item. Only when 4 or more spaces does remark fail to parse the indented list item.
With CommonMark, it seems like the required number of spaces to produce a similar result is 6 spaces instead of 4.
Debugging
I've put in a few hours stepping through the code. It's a bit tedious and difficult to understand, but it would seem that the normalListItem function eats up the - at the beginning of the first line, causing the difference in indentation to be 2 characters greater, which may be causing the symptom observed.
Unfortunately, with my limited experience, I am unsure how to continue with debugging or coming up with a fix.
Additional Information
This behavior is similar to #315 so they might be related.
