Bug 1874606 - Add a test for a WebKit / Blink bug where they incorrectly simplify percentages inside calc() in background-position longhands. r=layout-reviewers,jfkthame

Browse source 
See https://bugzilla.mozilla.org/show_bug.cgi?id=1874606#c3 (and the
test is self-explanatory, it's just a copy of
background-position-negative-percentage-comparison.html but with the
longhand expanded).
