I don't think we ever register WeakMap polyfill.

Oh, whoops, I was used to my original implementation which had passed this through as a feature argument to polyfill.io . I'll see about fixing this up.

Noting that this should not cause breakage for users without WeakMap support, as in later iterations of the new rememo release, it was made to be an optional enhancement.

This pull request seeks to upgrade the
rememodependency from 2.3.4 to 2.4.0 .View Changelog
Notably, the new version improves support for nested dependants, which is important for the
getBlockselector which otherwise has its cache busted much more frequently than desired, having performance impact on frequent block changes (such as those proposed in #4955).Testing instructions:
Verify that there are no regressions in the behavior of block changes.
Note that block changes should only incur rerenders to the relevant block†, e.g. using React Developer Tools Highlight Updates feature.
Ensure unit tests pass:
† There are still some unnecessary rerenders, though not nearly as bad as original in #4955 where every block would re-render.
