Comment:
Thanks for taking the time to do that debugging ribbonz, it really helped
me find this faster.
Basically we don't draw this text because our port does not implement
various "complex text" methods in WebKit. Specifically
Font::floatWidthForComplexText() is called when this optimizeLegibility
CSS rule is defined, but our unimplemented version just returns 0. I think
after that WebKit gives up rendering the text.
I'm not sure how quickly I can properly implement these methods, but I
suspect we could get by with at least implementing something basic.
Funnily enough, our port is not the only one suffering from this. In
certain cases Chrome won't render text with this property defined, and
like us, webOS won't render text at all!

In that sense I think WebKit screwed up when implementing this and should
have better handled ports not implementing these functions. Of course they
may have fixed this problem since then but our port has not been updated
in a very long time.
For now I think I'll continue working on updating our port and let this
issue stand by for now. But at least we now know why it happens.
