Linter does not run against changed markdown files in a PR #164
Description
When markdown files are created or updated in a PR, the linter does not pick up violations of the markdown rules for these files and allows them to be merged. However, when another PR is created, the linter will then detect that the files from the first PR are invalid and flag them as such.
Need to investigate whether it is a configuration issue with the linter, or an issue with the linter itself.
