Description of Change

  • When an object passed across contextBridge has a property getter that throws, rethrow to the caller instead of silently dropping the property and continuing the call — consistent with how array elements are already handled.
  • Same for an Error argument whose message getter throws.
  • Adds a spec covering both cases.

Checklist

Release Notes

Notes: Fixed an issue where an exception thrown by a property getter on an object passed through contextBridge was swallowed instead of being thrown back to the caller.
