<title>CSS Test (Transforms): Fixed Background (will-change: transform)</title>
<meta name="assert" content='"Fixed backgrounds on the root element are
affected by any transform specified for that element. For all other
elements that are effected by a transform (i.e. have a transform applied
to them, or to any of their ancestor elements), a value of fixed for the
background-attachment property is treated as if it had a value of scroll."
This tests that adding will-change: transform to an element with a fixed
background doesn't change rendering from scroll background.'>
