Not sure if this is a bug but thought I'd see if anyone else is experiencing it before raising a support ticket. I've created a dashboard in Enterprise 10.9.1 which contains a map with a simple point feature layer (from a hosted feature service). I also have a list element (based on the same point layer) in the dashboard which is filtered by the user making a selection on the point layer on the map which works as expected until......

Image shows point selected and list filtered correctly
...the map is panned a reasonable distance away from the selected point and the selection is removed from both the list and the box that appears next to the select tool showing how many records are selected. The point feature that I had selected still remains highlighted on the map though.
From a little bit of experimenting it seems like the selection fails once I've panned the map horizontally about a full map window's width away from where I started, irrespective of what scale the map is at. I thought it might have something to do with the Render Only When Filtered setting for the list but I still get the same result whether that is applied or not.

Image shows map after panning away and back again, selection is lost (despite highlight) and list unfiltered.
