@nschonni, could you provide an example, please? I can paste the current version of the file from that PR (https://raw.githubusercontent.com/nschonni/EntityFramework.Docs/586e4ebdb728a6b1719b77b4a29ed75a03afc5e1/entity-framework/core/logging-events-diagnostics/interceptors.md) into the demo page (https://dlaa.me/markdownlint/) without triggering any instances of MD033.

@DavidAnson ah, from the PR, I had stripped the commented out code that was triggering the issue. But if you paste the current file, you'll see the same issue.
Second file looks like something they missed because the rule is off

The CommonMark and HTML specs don't agree on what constitutes a comment. The CommonMark spec is explicit that "--" is NOT allowed in a comment: https://spec.commonmark.org/0.29/#html-comment. However, their dingus ALLOWS "--" within a comment. So I think my commit above stands (though it reveals a new library issue in the docs/docs repository).
