Negative values invalid for `marginBottom`?

[darsee]

I see restrictToPositive is set to true for marginBottom (and the tests assert that the value cannot be negative) - is this correct?

cssstyle/lib/properties/marginBottom.js

Line 6 in ba34962

const val = parsers.parseMeasurement(v, true);

cssstyle/lib/parsers.js

Line 230 in ba34962

exports.parseMeasurement = function parseMeasurement(val, restrictToPositive = false) {

cssstyle/test/properties.test.js

Lines 815 to 817 in ba34962

	it("margin-bottom should not set / get negative length", () => {
	testPropertyValue("margin-bottom", "-10px", "");
	});

I understood that its value can be positive, zero, or negative (see https://developer.mozilla.org/en-US/docs/Web/CSS/margin-bottom).

Thanks for the quick response!
