Known issues

Unsafe Scripts

You may have to Load unsafe scripts from the omnibox shield icon to allow connecting to the insecure websocket endpoint ws://localhost:9222:

Red herrings

Depending on the current build, if you run the container interactively you may see things like this on the console:

[0501/162901.033074:WARNING:audio_manager.cc(295)] Multiple instances of AudioManager detected
[0501/162901.033169:WARNING:audio_manager.cc(254)] Multiple instances of AudioManager detected

In most cases, these messages can be safely ignored. They will sometimes change and eventually as things are updated in the source tree, resolved.
