For navigation timing, half of the implementation is in WebKit. The other half
is in the browser's network stack which is implemented separately by each port
of WebKit. Currently Chrome has it implemented and thus the API is flipped on
in WebKit. Safari has not implemented that side so the API is disabled in

No. You are right, I didn't think of it that way. However, the converse is
equally concerning. If we had run the test more often in Safari than Chrome, it
would appear that we didn't have a conforming engine at all.

I'd be in favor of a second report that separates out browsers. If for no other
reason than to feed bloggers and the like who enjoy quoting numbers like
"Browser X passes Y% of conformance tests."

However, that doesn't necessarily fully address the concern above.
