Fixes #894
Adds a roundtrip test that passes in this branch but fails on main.
Cause description
tokensWithCheckedfunction calledmapTokensto detect and modify checkbox nodes in the AST.mapTokensacts recursively on the entire sub-AST passed in, so it would modify AST nodes of nested lists, removing their checkboxes.The bug was extra confusing to diagnose because 1. also meant that
tokensWithCheckedmodifies the original AST. I was logging the AST before the call totokensWithCheckedto try to understand the issue, but realized after that the logged AST was being modified after being logged, so I was seeing the modified version.That's gross. So, in this PR I've also made it so
tokensWithCheckeddoes not modify the original AST, it instead returns a modified sub-AST.
