JavaFX WebView and markdown rendering...

[Kevin Rushforth]

No, WebView does not render markdown. That is something done on the 
server. Some websites (e.g., GitHub) will render markdown by generating 
the appropriate HTML on the fly.

I can reproduce what you are seeing using a GitHub gist containing a 
simple markdown file:

https://gist.github.com/kevinrushforth/26a76c5ccd2d41df798c2a29542a3414

That page is rendered correctly in Chrome and Firefox. It shows both 
bold and italic for the last line of text (the one that reads "This is 
some bold text and some italicized text"). The"GitHub openjdk/jfx" link 
also works and takes you to the openjdk/jfx repo on GitHub.

When rendered using WebView (on Windows 11 at least), everything is 
correctly rendered except the bold text. The link works correctly.

I'm not sure where the problem is, but I can file a bug. It might be 
related to synthetic bolding of text...we've had other bugs in that area 
in the past. I can't recall whether there are still outstanding bugs.
