1905392 - OriginControls.getState throws "policy.extension.tabManager is undefined" when an extension is starting up

Status: RESOLVED FIXED

I just encountered a test failure, with a stack trace similar to bug 1876359.

Upon investigation, it looks like OriginControls.getState is called for an extension that is in the middle of extension startup. We should handle that gracefully instead of breaking the UI.

I'm drawing the conclusion that the extension in the test is in the middle of startup, because policy.extension being set implies that the extension has done the minimum to start up, but policy.extension.tabManager being undefined implies that the "startup" event has not fired yet, which is responsible for initializing extension.tabManager.
