This particular is slightly different from the others because it does not have a hard dependency on `Zone`. It doesn't actually use `Zone` directly during the patch because the patch just sets a `legacyPatch` global. To maintain consistency, this continues to use global `Zone` and does _not_ accept `Zone` as a parameter. While it's using a global in an inconvenient way, this isn't a problem right now because it doesn't cause or require a dependency on a top-level side effect. PR Close #53443
