htmlText in HTML5

in the feature matrix the htmlText feature is set as “partial” for HTML5: where can I see which parts of this feature is supported in HTML5? It looks like the support is really poor, I can’t even use
Alternatively, how can I handle formatted (newline, bold, colour etc…) texts?

Support for color, size and face are supported (I believe), as well as line breaks, most other things are stripped at the moment.

@GiG Can you try ?
