This restores the behavior pre-273934 at main when getting the computed style of pseudo-elements like "::placeholder" / "::file-selector-button".

getComputedStyle() support for these pseudo-elements is currently broken (and has always been), since we return the element style instead, but this change
makes it so we stop asserting.
