RTCDataChannel undefined after registerGlobals() and LivekitReactNative.setup()

Environment

Package	Version
@livekit/react-native	2.11.0

New Architecture	disabled (newArchEnabled: false)
Build method	EAS Cloud Build
Device	iPhone 16 Pro, iOS 26.5

What happens

After calling both registerGlobals() and LivekitReactNative.setup(), RTCDataChannel is undefined while all other WebRTC globals are correctly registered:

registerGlobals();
console.log(typeof (global as any).RTCPeerConnection);  // "function" 
console.log(typeof (global as any).RTCDataChannel);     // "undefined"
console.log(typeof (global as any).MediaStream);        // "function"
console.log(typeof (global as any).RTCIceCandidate);    // "function"

Calling new Room() throws: TypeError: Cannot read property 'prototype' of undefined

Setup

registerGlobals() called at module level and at app entry point (_layout.tsx).

LivekitReactNative.setup() added to AppDelegate.swift — both manually and via
custom Expo Config Plugin. Verified present in built binary via npx expo prebuild.

newArchEnabled: false set at root level in app.json.

Key observation

Only RTCDataChannel is missing. All other WebRTC globals (RTCPeerConnection, MediaStream, RTCIceCandidate) are correctly registered. Not a general registerGlobals() failure.

Question

Is there a known issue with @livekit/react-native-webrtc@144.1.0 where RTCDataChannel is not exposed as a JS global?
