Pending block editor revisions for WordPress 5.4 will make use of `window.URL` and `window.DOMRect`. These are not available in Internet Explorer (or pre-Chromium Edge for `DOMRect`) and must be polyfilled to avoid script errors. The changes make use of the existing polyfill pattern, and existing `polyfill-library` dependency. The dependency is bumped to the latest version, since the previous version did not include the `DOMRect` polyfill. Props jorgefilipecosta. Fixes #49360.
