The site seems to load properly in a Nightly build. This crash seems to be a debug-only assertion, for a condition that we handle with graceful fallback for release builds:
https://searchfox.org/mozilla-central/rev/1b79e3d893035e3ab581401bc70f2e5198c2fa73/servo/components/style/values/generics/calc.rs#1335-1344

let max_cmp_min = match max.compare(&min, PositivePercentageBasis::Unknown) {
    Some(o) => o,
    None => {
        debug_assert!(
            false,
            "We compared center with min and max, how are \
             min / max not comparable with each other?"
        );
        return;
    },

Adding dependency on bug 1613491 which is where we added this assertion (years ago), and triaging as S3 given that we handle it gracefully for release builds and this isn't a fuzzblocker or anything at this point.

low-priority ni=emilio who might be interested to take a look at the pernosco session given that he added the assertion here.

Attachment: reduced test-case.

Ohh, so I think it's just a bogus assertion. In this case the center is positive, min and max are negative, so we know the center is greater than both, but we still can't compare the min and max because they're different units, so it can't be simplified.

In this case the center is positive, min and max are negative, so we
know the center is greater than both.

But we still can't compare the min and max because they're different
units, so it can't be simplified.
