When I wrote that I was thinking even for forced flushes from the author, but thinking more about this it could make sense to have an exception for forced style flushes so that getting the computed style doesn't behave differently in and out of these subtrees.

`getAnimations({subtree: true})` will be a bit of a performance cliff if we require that it account for animations within hidden content-visibility subtrees but on the other hand it may not be too common and we already have the same issues with select all and find in page.

Do you have a preference?
