Exiting sync_playwright() cancels pending tasks in the loop it owns. The done callback that reports handler errors called Future.exception() on the cancelled future, which raises CancelledError and made asyncio log it. Fixes: https://github.com/microsoft/playwright/issues/43463

Summary
sync_playwright()cancels the pending tasks in the loop it owns. The done callback attached to event handler tasks calledFuture.exception()on the cancelled future, which raisesCancelledError, so asyncio logged "Exception in callback" for a route handler that was still waiting.Fixes #3272
