When the value of the main Lookup is changed, the value in the Parameterized Lookup is not cleared in the Modern UX as it does in Classic UX.
The Steps To Reproduce use the Department and Location parameterized lookup. However, it occurs with any paired parameterized lookups: Project Type & Project Category lookups.
STEPS TO REPRODUCE:
1. Log in to the Modern UX
2. Add the Department and Location fields to the Projects Grid or into a Blueprint
3. Change the value of the Department
Expected Results: The Location is a parameterized lookup and is dependent on the Department value. Because the Department value is modified, the Location should be cleared out as in the Classic UX.
Actual Results: The Location value is not cleared out.
