In most Shiny apps, once the connection is dropped, the client-side Shiny code grays out the UI. I have some apps, however, that don't gray-out the UI when I explicitly kill the server process. Reducing these apps to a non-graying-out reprex will be decently tough and take a while, so I thought I'd ask ahead-of-time if others have encountered scenarios where this happens, and what characteristics of apps might cause this.
Also, FWIW, this happens reproducibly on both localhost (with just shiny) and remote host connections (the latter with shiny-server).
Has anyone else ever had an app that reproducibly did not gray-out the UI when the connection to the server was broken/dropped?
