Re: [csswg-drafts] [css-transforms-1] Should will-change: transform be treated as transform for background-attachment:fixed? (#6951)

I believe that [this paragraph](https://drafts.csswg.org/css-will-change/#ref-for-propdef-will-change%E2%91%A2%E2%91%A0) from [css-will-change] applies here:

> If any non-initial value of a property would _cause rendering differences_ on the element (...), the user agent should use that alternate rendering when the property is specified in `will-change`

(given that [css-transforms] [explicitly states](https://drafts.csswg.org/css-transforms/#module-interactions) that "Transforms _affect the rendering_ of backgrounds on elements with a value of `fixed` for the `background-attachment` property"). So the current behavior of Firefox and planned behavior of Chrome are correct.
