All sources of documentation (for example https://developer.mozilla.org/en-US/docs/Web/CSS/will-change#via_script and ) I read about will-change suggest that we add it programmatically and remove it after it's served its purpose, rather than having it enabled by default.

Have you considered adding it as a one-off effect in this component and then removing it on cleanup?

@tyxla You're thinking of adding it when the popover opens ? We can use a translateZ(0) instead of will-change to get the same result !

Have we tested adding it only on hover/focus ? Or what about using the contain CSS property instead?

I think adding it on :hover/:focus can be too late since the browser won't be able to do the optimizations before performing the actual element transformation.

@include reduce-motion("transition");

&:hover {
