NestedFormController not triggering useDirtyInputTracking when deleting persisted nested record

[gap777]

• NestedFormController sets the value on the destroyed input without triggering an event: destroyInput.value = "1";
• useDirtyInputTracking will only updated based on input or change events

Thus, NestedFormController will not mark the hidden input dirty.

Can you fix NestedFormController?

Thanks!
