Steps to reproduce

  1. Wrap the text in Markdown Header with HTML underline tag
  2. Use Markdown Bold tag along with HTML underline tag

Expected result

  1. The Header should be rendered as an Header (Bold and in large text)
  2. When using underline in conjunction with bold tag the output should show both the underline and bold style on the text

Actual result

  1. The header looses its bold styling and text size becomes small
  2. When underline tag is present inside the bold tag only underline is rendered while when underline is outside the bold tag the only the bold styling is rendered

We don’t support this. Moved to feature request.

FWIW, I’ve just discovered that using span tags with the appropriate CSS — span style="text-decoration: underline;" — produces the same results as in the initial description.
