prompt:
Changing fields retains a compatible operator and resets an incompatible one is violated by the widget projection.

A filter-builder row uses schema capability lists to determine available operators and reset incompatible operands when its field changes. This example checks: Changing fields retains a compatible operator and resets an incompatible one.
