Research direction

Start by creating a fresh React Native 0.87 sample on Windows, running the Android app, and pressing "j" from Metro to reproduce the blank Dev Tools screen. Use the attached screenshot and reported environment details to compare the rendered result; done means Dev Tools opens with its expected content instead of a blank screen.
