We're internally treating the minmax() function as a list of CSSValue instead of a CSSFunction. The problem with that is that a declaration like -webkit-grid-definition-columns: minmax(10px, 50px) will be transformed, when asking for "element.style.webkitGridDefinitionColumns" in "10px 50px" i.e. a string with a list of values instead of "minmax(10px, 50px)" which is the correct value in this case.
Setting a dependency as I prefer the dependency to land first as it will drastically simplify the patch for this test (significantly reducing the amount of code for the tests)
