Summary audi.com: Deactivate the <model> element feature to avoid a name conflict

The audi.com configurator puts its engine panel inside a custom <model> tag. WebKit reads that as an instance of the Immersive Web built-in 3D-model element and always gives it a fixed 300x150 box that can't show anything inside it, so the whole panel disappears. Chrome (and Firefox) do not support this new standard proposal, and treats <model> as an ordinary unknown tag and shows the panel. Best practice for custom elements is to contain a hyphen (e.g., <audi-model> would have been safe). We can work around this issue for Audi's configurator by turning the <model> element off when visiting this site, since it does not expect a true 3D-model element for its content.
