dartdoc strips markup from summary line

[Hixie]

Compare this page:
http://docs.flutter.io/flutter/material/Icons-class.html
...to this page:
http://docs.flutter.io/flutter/material/Icons/ac_unit-constant.html

Notice how in the latter page, the icon is visible since the markup controls the font that is used, while in the former page, the icon name is visible rather than the icon, because the font styling is lost.

I worked around this by wrapping the entire /// line with <p>.

Possibly fixed by #1207? I'll double check.
