@igoroctaviano this is probably unrelated, but as you work on this, maybe easier to check ... In this study https://viewer.imaging.datacommons.cancer.gov/slim/studies/2.25.68803095896966276583382138924964839274/series/1.2.826.0.1.3680043.10.511.3.62843955543203053464781191551511085, if I zoom in and after that toggle parametric map visibility on, zoom is reset to show the entire slide.
