Grouping by a lookup attribute in the Modern UX task grid causes a continuous loading loop if the referenced subobject row has been deleted․․․․
ERROR MESSAGE: "Loading Data" (Infinite loop)
The task grid fails to load correctly when grouping is applied.
Users experience a scrolling "loop" at the bottom of the page.
Lookup values are not retained in the task object after the source subobject row is deleted.
Occurs in the Modern UX task grid when an attribute relies on a dynamic lookup querying a subobject.
Ensure the query handles null or orphaned values for deleted records.
Expected Results - You can scroll without issue
Actual Results - The page will seem to 'loop' on Loading Data
