/**
* Test Parsedown against the CommonMark spec, but less aggressive
*
* The resulting HTML markup is cleaned up before comparison, so examples
* which would normally fail due to actually invisible differences (e.g.
* superfluous whitespaces), don't fail. However, cleanup relies on block
* element detection. The detection doesn't work correctly when a element's
* `display` CSS property is manipulated. According to that this test is only
* a interim solution on Parsedown's way to full CommonMark compatibility.
