I try to display a map in a shiny app that displays two spatRaster side by side with the leaflet addSidebyside() function. In principal this works. However, if I want to change the background map using another provider (e.g. positron), the raster images are not displayed anymore. How can I get a positron base map with two overlaying raster side by side?
