Hi,
If a 3D rotation is applied to a WebView the following exception is thrown.
There is no issue if there an effect applied to the WebView.
No reproducible with a simple Button instead of a WebView.

Moreover, when the 3D rotation works (with an effect applied) the mouse coordinates are no longer trigger the correct "hyperlink" of the WebView content. The WebView seems to stay in a 2D environment.
Thanks.
