On iOS 26 beta8, if a view's subview contains a WKWebView, using the CALayer's renderInContext method fails to capture the pixel

I’m experiencing an issue in WKWebView on iOS 26 Developer Beta 8. If a view's subview contains a WKWebView, using the CALayer's renderInContext method fails to capture the pixel at the current point, and the console outputs "unsupported surface format: &b38".

The following code snippet was functioning as expected on iOS 18 and iOS 26 beta 1. However, it no longer works in the latest beta.

Is this a known bug in the current iOS 26 betas, or is there a recommended workaround?

- (BOOL)isTransparentAtTouchPoint:(CGPoint)point layer:(CALayer *)layer {
    unsigned char pixel[4] = {0};
    CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
    CGContextRef context = CGBitmapContextCreate(pixel, 1, 1, 8, 4, colorSpace, (CGBitmapInfo) kCGImageAlphaPremultipliedLast);
    CGContextTranslateCTM(context, -point.x, -point.y);
    [layer renderInContext:context];
    CGContextRelease(context);
    CGColorSpaceRelease(colorSpace);
    CGFloat alpha = pixel[3] / 255.0f;
    return alpha < 0.01;
}
