    Description

      Be able to keep the original image displayed in an Image until the changed source image is available. Currently, if it takes time to load an image after the source is changed then there will be a case of nothing being rendered before the new one is shown. Even if it loads quickly then it can cause a visible flicker in this case.

      Therefore, having an option to display the old image until the new one is ready might be desired for cases like this.
