Markdown conversion doesn't work with document titles

The “Convert Markdown to bold and italics” flag in the Transformations section of the Compiler doesn’t work with document titles.

I know that document titles are plaintext, which is why they can’t be formatted independently. However I’m not sure why this limitation applies to Markdown conversion. Document titles clearly have some formatting done to them by way of the Formatting panel. It would be great to have some specific formatting choices for titles!
