Gestures don't work when ModelViewer is inside ListView

[jakub-cosmose]

Describe the bug
No scaling or rotating can be done when the component is inside ListView.

To reproduce
Steps to reproduce the behavior:

1. Put ModelViewer inside ListView, e.g.

         ListView(
          children: [
            Container(
              height: 300,
              child: ModelViewer(
                src: 'modelUrl',
                alt: 'A 3D model',
                ar: false,
                autoRotate: true,
                cameraControls: true,
              ),
            )
          ],
        ),

2. Try gestures

Expected behavior
Gestures should work

Additional context
The internal WebView should handle all gestures by adding the following property to the constructor:

      gestureRecognizers: <Factory<OneSequenceGestureRecognizer>>{
        Factory<OneSequenceGestureRecognizer>(
              () => EagerGestureRecognizer(),
        ),
      },

Alternatively, there should be a way for the client app to enable that behaviour.
