Fullscreen working great, but splitscreen not resizing to it's visible bounds.

Nobody has claimed this yet.

Does your splitscreen automatically resize with this demo's codebase? If so, can someone point to what is causing the MapView to resize?

I don't see my map resizing when transitioning from splitscreen. I have the sample app working in fullscreen mode and in splitscreen the `MapView` doesn't resize and the map is therefore not centered in the split layout.

I see that nothing interesting happens in the `onStableAreaChanged` callback, and it seems mapContainer.setSurfaceSize is only ever called with `w=800` and `h=400` from the initial `onSurfaceAvailable` callback in `MapRenderer`. I would assume, and I have tried, that the `setSurfaceSize` would be called after the app receives a new layout size in `onStableAreaChanged`. But i'm reading the the `width` and `height` of the `Rect` in `onStableAreaChanged` excludes the system UI components like the `zoom, hamburger menu, and Test button`. But the map is behind those system UI components.

So now i'm confused and unsure if this demo actually accomplishes the resizing.

I've tried setting the `mapContainer.setSurfaceSize` to `stableArea.width() + stableArea.right` and `stableArea.height() + stableArea.top` in the `onStableAreaChanged`, and this works for splitscreen, but going back to fullscreen it causes issues with not receiving the proper dimensions. It's also seen in the screenshots that the mapView is outside the "stableArea" (the stablearea has a blue rect drawn)

I must be missing something here. Obviously I can store the initial `width` and `height` from `onSurfaceAvailable` surfaceContainer, and revert back when the layout size change, and leep track of what's the biggest layout size, But I don't like that.

Start by reproducing the sample app in fullscreen and split-screen modes, then trace onSurfaceAvailable, onStableAreaChanged, and MapRenderer's mapContainer.setSurfaceSize calls. Compare the stable-area dimensions with the visible MapView bounds in both transitions. Done means the map resizes and remains centered when entering and leaving split-screen without breaking fullscreen.
