Why are these font-size tests skipped?


135	ref-pref(font.size.variable.x-western,16) skip-if(styloVsGecko) == font-size-16.html font-default.html
136	ref-pref(font.size.variable.x-western,16) skip-if(styloVsGecko) != font-size-24.html font-default.html

We may not really need to skip them, but in general, I think tests in reftest-sanity doesn't really make much sense for styloVsGecko test, because those are mostly for checking handling of the various annotations.

In styloVsGecko, we have a very special reference page (which is the same page rendered in different engine). I have no idea how reftest harness handles this case, but I don't think it's worth worrying about reftest-sanity for styloVsGecko. I would suggest we should probably just skip the whole directory for styloVsGecko.
I agree with xidorn. As long as these tests are passing in stylo-vs-stylo mode I don't think it's worth investigating, since we're turning off styloVsGecko soon anyway.

From previous discussion on email, it seems to me we are not turning off styloVsGecko soonish. We may still want to see it when we work on Android support.

But either way, the reftest sanity test wasn't designed for this kind of special mode, and doesn't make sense in many cases. If we want to check sanity for styloVsGecko, we should design an independent suite of sanity test, but that's probably not worth.
