Description jay 2007-10-12 14:33:34 PDT
requiredFeatures combined with switch provides a relatively easy way for the author to create workarounds.

but not if it isn't supported....

test for static support
Comment 2 jay 2007-10-12 14:37:31 PDT
the attachment renders as "RDF"

however as static requires all features to be supported and font is not supported the result should be "3"
as per mozilla... 
opera does support font and displays the glyph for background of the new SVG logo
Comment 3 Eric Seidel 2007-10-14 00:56:32 PDT
Interesting.  This shows two bugs.  1.  We shouldn't be claiming to support "static" when we don't support fonts.  2.  We are rendering the contents of <title> elements, which we should not do.
Comment 4 Eric Seidel 2007-11-05 18:17:50 PST
Ah!  We're not rendering <title> elements, it's being used by a tref.  So the only bug here is that hasFeature reports too many features for WebKit (since we don't support SVG fonts).

Patch to make our feature strings match reality

This patch should make our feature strings match reality.  I've not yet run the layout tests to get an updated patch for those yet.
Comment 6 Eric Seidel 2007-12-19 03:51:15 PST
Of course whenever Niko's font patch lands, we'll have to re-enable a bunch of these strings again!
