onMessage on Window does only accept messages from content-script. Messages from Background or Popup are never-resolving Promises.

Version

6.0.1

Current Behavior

A onMessage listener in the window context currently only reacts to messages from content-script. Messages from Background or Popup are never-resolving Promises.

Expected Behavior

Messages from Background or Popup to the window context should work.

Steps To Reproduce

1. add setNamespace and a onMessage listener & on the window context
2. add allowWindowMessaging and a send message to the content-script context -> the sendMessage resolves / works
3. add a send message to the popup context -> the sendMessage never resolves / doesn´t work

Anything else?

Same here. Can someone confirm this?

Hey... Did figure that out: it was a missing "tabs" permission. Was then giving up on it rather then adding extra permissions.

Thanks for the reply @thomasf1 ! I do have tabs permission added in my manifest though.
