Setting IsSwipeNavigationEnabled = false does not disable swipe navigation

What happened?

During initialisation of WebView2 our code sets the following properties:

         IsSwipeNavigationEnabled = false;
         IsPinchZoomEnabled = false;

We did this in May 2023 to prevent swipe gestures navigating forward/back and worked perfectly when we were using version 1.0.1661.34 of the WebView2 package. But we upgraded to version 1.0.2151.40 in December and now it is possible to use a swipe gesture to trigger forward/back navigation (we can see the circle with an arrow dragged in from the left/right edge of the screen when this happens).

I have also recreated the issue after upgrading the WebView2 package to 1.0.2478.35 (with Edge 124.0.2478.51 installed).

Based on other issues here I also tried adding the following code, which made no difference to the behaviour:

         var options = new CoreWebView2EnvironmentOptions("--disable-features=ElasticOverscroll,msEdgeMouseGestureSupported,msEdgeMouseGestureDefaultEnabled --enable-features=kEdgeMouseGestureDisabledInCN");
         var env = await CoreWebView2Environment.CreateAsync(null, null, options);

I have also tried downgrading the WebView2 package back to 1.0.1661.34, whilst retaining the latest Edge, and can recreate the problem then too, so to me at least it appears the runtime may have regressed this issue?
