 There are a handful of polyfill libraries listed as `devDependencies` that
 have available updates:

 - `objectFitPolyfill`: Core has `2.3.4`, latest is `2.3.5` (introduced in
 [50048]).
 - `formdata-polyfill`: Core has `3.0.13`, latest is ``3.0.20` (last
 updated in [44728]).
 - `polyfill-library`: Core has `3.42.0`, latest is `3.103.0` (last updated
 in [47238]).

 These are block editor related, but they do not appear to be
 [https://github.com/WordPress/gutenberg/blob/trunk/package.json listed as
 dependencies in the Gutenberg repo] anymore.

 We should:
 - Confirm they are still required.
 - Remove them if not.
 - Update to the latest versions.

 The scenarios where they are used need to be identified and tested.
