Nested lists of roman numerals that differ in casing fail to parse properly

[manutiedra]

If I try to parse this:

1. **Introduction to Legal Principles**
   1) Historical Context
   2) Core Doctrines
      i. Doctrine of Precedent
      ii. Doctrine of Equity
   3) Sources of Law
2. **Civil Procedure**
   A) Pleadings and Motions
      a. The Complaint
      b. The Answer
      c. Pre-trial Motions
   B) Discovery Process
   C) Trial Proceedings

I get the proper AST:

However, if I change the list before the roman numerals in lowercase to a list with roman numbers in uppercase like this:

1. **Introduction to Legal Principles**
   I) Historical Context
   II) Core Doctrines
      i. Doctrine of Precedent
      ii. Doctrine of Equity
   III) Sources of Law
2. **Civil Procedure**
   A) Pleadings and Motions
      a. The Complaint
      b. The Answer
      c. Pre-trial Motions
   B) Discovery Process
   C) Trial Proceedings

the AST generated is wrong, as it didn't create a third level for the list with lowercase roman numerals:

Hi, I was able to reproduce and dig into the issue a little bit, and I may have a solution.

Adding spaces for indentation before the third-level nested list element appears to resolve the issue. Specifically, I tried adding one extra space to the nested list items opening:

II) Core Doctrines
   i. Doctrine of Precedent
   ii. Doctrine of Equity

to:

II) Core Doctrines
  ->i. Doctrine of Precedent
  ->ii. Doctrine of Equity

Resulting in the following markdown input:

1. **Introduction to Legal Principles**
   I) Historical Context
   II) Core Doctrines
       i. Doctrine of Precedent
       ii. Doctrine of Equity
   III) Sources of Law
2. **Civil Procedure**
   A) Pleadings and Motions
      a. The Complaint
      b. The Answer
      c. Pre-trial Motions
   B) Discovery Process
   C) Trial Proceedings

From what I can gather, the normal indentation rules about nested lists are causing the issue, where there was not enough indentation away from the list item delimiter ) in the line II) Core Doctrines.

Does this help explain the unexpected behavior?

Good catch. I missed this detail when reading the issue in the first place. Actually, this is not unexpected but part of the indentation rules for list items in the spec.
