+<!-- In this test, the div |fixed| is fixed with respect to the
+ page's root scroll frame, but there's also a subframe |scrollbox|
+ which is async-scrolled and which generates a container layer
+ (because of the opacity), so that its async transform is on an
+ ancestor layer of |fixed|'s layer. We are testing that this
+ async transform is correctly unapplied to keep |fixed| fixed. -->
