The MediaPlaybackError class + MediaPlaybackErrorExplainer feature is well designed — the HEAD probe that diagnoses 404s and wrong content-types in the error overlay is a great DX improvement. The listen-to-runtime-errors.ts change to pass the full error object (instead of destructuring into a plain object) is the correct fix to preserve instanceof MediaPlaybackError downstream. One nit on the docs.
