Dev tools covers half the page until window is resized

[ariamckinley]

When initially running yarn electron, the dev tools inspector covers half the page. As soon as a viewport resize event is triggered, it corrects itself. Subsequent reloads do not re-trigger this issue, it's only present on initial render.

I thought maybe it was due to [email protected], but tried rolling back to 1.4.3 and the issue is still present.
