If an Emscripten app is in relative mouse mode and the user presses Escape (or whatever is appropriate), then the pointer lock is broken by the browser. This keeps track of those losses, and next time the user presses a mouse button down on the canvas, if the app is still meant to be in relative mouse mode, we will attempt to regrab the pointer. This makes it much more seamless for things like first-person shooters, and the app doesn't need any manual intervention.
