This test has started failing since r278304, in particular one assertion in the test (added in the aforementioned change) fails as follows: FAIL computedStyle("background-color", "lch(from peru calc(l * 0.8) c h)") should be lch(49.80138% 54.003296 63.680317). Was lch(49.80138% 54.003284 63.68035). Which seems like a precision issue somewhere (perhaps the test demanding too much precision here?)
Interesting. I wonder where things could be differing from glib to the cocoa platforms here, as I would kind of expect double / float arithmetic to be the same. Perhaps compiler flags or something. But yeah, making these tests a little more lenient somehow makes sense to me.
