Anybody know why the webbox quickly appears before showing right on it's parent? https://i.gyazo.com/83127205b6fb2cffd46fd7505f72cd77.mp4 This is how i call it: ``` public void InitializeWebbox() { var hWnd = new WindowInteropHelper(this).EnsureHandle(); sliderBox = new Webbox(_sliderBox, hWnd); sliderBox.AllowsTransparency = false; sliderBox.Topmost = false; WebBrowser sliderBrowser = sliderBox.WebBrowser; sliderBrowser.Navigate(new Uri(sliderUrl)); } ```
