2722593 - WDA: Error downloading files from Webdynpro ABAP app embedded into Fiori

Symptom

When downloading a file from a Web Dynpro ABAP called from Fiori Launchpad, an error occurs or the file isn't downloaded.

Most common errors are ASSERTION_FAILED on class CL_WDR_CLIENT_SSR_LS or a timeout.

On some cases removing the parameter sap-xapp-state from the URL can work as a workaround to download the file.
