[HTML5] Fix target_fps when window loses focus.
We don't get updates when the window is unfocused/minimized, so we must
detect the situation where the counted ticks start drifting away
resulting in more frames drawn than needed.
This commit adds a check to ensure that the target ticks do not drift
away more than one second.
