To Reproduce Steps to reproduce the behavior:

  1. Enable Strict mode (in OnCreate(...))
var vmPolicy = new StrictMode.VmPolicy.Builder();
StrictMode.SetVmPolicy(vmPolicy.DetectAll().PenaltyLog().Build());
  1. Use the Shadow
       <shades:Shadows>
            <shades:Shadows.Shades>
                <shades:ImmutableShades>
                    <shades:Shade/>
                </shades:ImmutableShades>
            </shades:Shadows.Shades>
            <Label Text="Hello World"/>
        </shades:Shadows>

Screenshots (if applicable) It renders fine, but the debugger slows down considerably when using multiple shadows (since multiple exceptions are being printed) When hot-reload triggers, the exceptions are not being printed (presumably due to the cache?)
