AttributesTreeViewModel needs 4+ minutes to update

In ArcGIS Pro 2.1.3, I select in-service water meter point features (89K).

Diagnostic Monitor says "ArcGIS.Desktop.Editing.Attributes.AttributesTreeViewModel+<OnSelectionChanged>d_102.methodMoveNext  runs as a Task on FG for 4+ minutes" to update, greying-out the UI.


Is there any thing I can do to mitigate (C#) this update process since the user is likely NOT editing, but searching for attribute matches among in-service water meters?


In the ArcGIS Desktop 10.x environment, there is clear distinction between selecting and editing processes, since you have to turn-on editing.  In Pro, it's different.  Seems the Editing TreeViewModel must update in real-time on the foreground thread to prepare for selection of the Edit tab.


Any ideas?
