Opening a `--debug` app URL in another browser and hitting Alt-D crashes webdev

[kevmoo]

Ran serve --debug
Opened in a new chrome window. Great.

Not great: opened the app in my "normal" Chrome instance and hit Alt-D

Expected: a prompt or something about not being in the right Chrome instance.

Actual: got an ugly error message + stack and webdev terminated.

Unhandled exception:
Bad state: Could not connect to application with appInstanceId: 0063b450-5970-11e9-83ed-019000c0d304

Having the same problem. I tried using the latest master branch of webdev but still no luck. Works fine without --debug parameter.

dev_dependencies:
  build_runner: ^1.6.2
  build_web_compilers: ^2.1.1
  pedantic: ^1.0.0
  provider:
    git:
      url: https://github.com/kevmoo/provider
      ref: flutter_web
  webdev:
    git:
      url: https://github.com/dart-lang/webdev
      path: webdev
      ref: master
