Sadly, this is still an issue for WebKitGTK+, though only with web fonts. If all goes well, it should be fixed in the next release. It's only been rather recently that the libraries necessary to do this have existed stand-alone for the free desktop (with HarfBuzzNG 1.0).

In the past, HarfBuzz was embedded directly into libraries like Pango -- and this is the approach that Chromium on Linux used. Now that HarfBuzz is a standalone library, we can use it in WebKitGTK+ (where embedding dependencies is more culturally taboo).

The reason that Pango doesn't work for this usecase is that it's only designed to work with installed fonts. Firefox had a "hacky" subclass of some core Pango class that worked around the issue.
