Research direction
Start with the window.js stack locations around whenTabLoaded, _inject, and App.componentWillMount, then reproduce the blank devtools window with MobX 5.15.1. Inspect the tabs.get invocation and its reported signature error; done means the devtools opens and no matching-signature error appears.
