PopupEdit throws when the Grid is bound to DataTable or ExpandoObject

Triggering Edit in a Grid bound to a DataTable or ExpandoObject and with edit mode set to Popup throws an unhandled exception. This started to occur in 4.1.0 - the same code runs fine on 4.0.1

To reproduce:

  1. run https://blazorrepl.telerik.com/cduHQkPS34V0enTc50 (note this is the DataTable demo, but with changed edit mode)
  2. trigger edit mode
  3. observe the unhandled exception

Was the fix supposed to be in 4.2.0? 
If not, do you know when we could expect the fix?
