Markdown styles not render so close to actual Markdown rendering

[mickaelistria]

From a simple markdown

_italic_
**bold**
~stroke~

I would expect that the TM4E grammar could extract the different styles (it seems it does as the tokens get a different color) and that the related Markdown styles get applied. However, it only changes the color, bold, italic and so on are not applied. I see the theme only defines the colors. Could it also define some other font attributes?
