I don't think that's necessary. Without a transition, this is *exactly identical* to just setting `opacity:0` by hand (and it doesn't matter whether or not you're a stacking context). With a transition, it's still *exactly identical* to just setting `opacity:0` by hand (and there's already author guidance recommending setting `will-change: opacity` in this case, for precisely this reason). If the transition happened *automatically* my opinion would probably be different, but it doesn't - the author still has to explicitly say `transition: opacity 1s` in their stylesheet, so either they *already* have a reflex for setting `will-change: opacity` as well and everything will do great, or they don't have that reflex and it's bad for any of their `opacity` transforms. I don't think we need to solve this for them. -- GitHub Notification of comment by tabatkins Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/12732#issuecomment-3399240740 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
