One contributor, Oskar Eichler, landed over twenty focused fixes across structured clone, event handling, and DOM-adjacent APIs, closing a broad class of prototype-pollution and spec-compliance bugs. Separately, a three-part PR series adds URL-based background image support across JavaScript, Android, and iOS.

The vast majority of today's pull requests, all from Oskar Eichler, target the same root problem: internal registries and object maps built as ordinary JavaScript objects, which silently break when a key collides with something on…
That pattern shows up everywhere. Event Emitter, in PR 58229, and AppRegistry, in PR 58197, both crashed or misbehaved on event or app names that shadowed inherited properties. The same fix landed for the legacy bridge's callable module lookup in PR 58199, and for native event type caching in PR 58203. The fix is…
The other major cluster is structured clone. Nearly a dozen PRs today — covering ArrayBuffers and typed arrays in 58219, RegExp internals in 58225, boxed primitives and BigInt in 58227 and 58211, Error causes and prototypes in 58207 and 58215, sparse arrays in 58209, and reentrant calls in 58205 — all tighten the…
A smaller but related batch fixed observer batching — Mutation Observer in 58237 and Intersection Observer in 58235 — where one stale entry could silently drop callbacks for every other active…
