Resolve invalid_runtime_check_with_js_interop_types warnings for JSDomException. Instead of directly catching the extension type JSDomException or checking e is JSObject, we catch generic objects, cast them to JSAny?, and check if they are JSDomException instances using isA<subtle.JSDomException>(). This avoids platform-inconsistent runtime checks that behave incorrectly under dart2wasm where extension types are runtime-erased.
Resolve _TypeError when casting generic exceptions to JSAny? under dart2wasm.
