WebCore contributor
Summary
NathanSolomon733 works primarily in WebCore rendering and style — inline layout, display lists, style invalidation — with a secondary line of IPC and focus handling in the WebKit layer. The pattern is performance rather than security: work is deferred or elided (InlineContent and InlineContentCache destruction moved off the hot path, ReleaseDisplayList batched over IPC, ElementDidFocus pushed to the next rendering update, `invalidateStyle()` removed from `setChecked()`, descendant style resolution skipped on transition to `display:none`) and caches are added or re-keyed (GlyphDisplayListCache dedup, DocumentSharedObjectPool, innerHTML prefix caching); one of the deferrals already produced a tracked iOS regression. The audit angle: deferred destruction and skipped invalidation both widen the gap between when an object is logically dead and when it is actually torn down or re-resolved, and the DocumentSharedObjectPool re-key from RegistrableDomain to SecurityOriginData moves a cache-sharing boundary — stale renderer state and cross-document reuse are the failure modes to probe.
