Will-change: opacity should create a stacking context for inlines
The spec [1] states that will-change: opacity should create a stacking
context for inlines in the same way that non-zero opacity does. This was
fixed by https://crrev.com/776581 ("Unify CSS grouping properties") but
we didn't have a testcase. This patch adds a WPT test of this behavior.[1] https://drafts.csswg.org/css-will-change/#will-change
