Summary:
Split from D1921.
- DifferentialChangesetParser doesn't have this property declared.
- We weren't providing a markup engine, which caused some warnings.
- This would cause failures if comment caches weren't present. Currently, they always will be though unless someone has wiped them explicitly in the DB.
Test Plan: Viewed a diff with inline comments, didn't get any warnings in the log.
