Given a simple Dart web app created with dart create -t web and the code updated to:

import 'dart:html';

Future<void> main() async {
  // TODO: Remove this delay when breakpoints in startup code work
  // https://github.com/dart-lang/webdev/issues/830
  await Future.delayed(const Duration(seconds: 1));

  methodThatThrows();
  querySelector('#output')!.text = 'Your Dart app is running.';
}

void methodThatThrows() {
  throw Exception("Oops");
}

When the exception is triggered, the pause event is PauseInterrupted instead of PauseException:

{
	"jsonrpc": "2.0",
	"method": "streamNotify",
	"params": {
		"streamId": "Debug",
		"event": {
			"type": "Event",
			"kind": "PauseInterrupted",
