        <pre>Very often view state changes happen one after another in a very short period of time, even in the same run loop iteration. For example, when you switch to the web view window, the view is focused and the active window flag changes as well. In that case we are sending two messages to the web process and the page updates its status according to the new flags in two steps. So, we could group all state changes happening in the same run loop iteration and notify about them all in the next iteration. This also prevents unnecessary changes of state when we quickly go back to a previous state, for example in focus follows mouse configurations if you move the mouse outside the window and then inside the window again quickly.</pre>
