Observed Behavior

When using DynamicForm's fieldOverrides with a PeoplePicker control with when you save the record the user field will remain blank. There are no errors thrown. The issue is when calling the onChanged event in the switch case 0 block the line
if (!(newValue[0].id === undefined || parseInt(newValue[0].id, 10).toString() === "NaN")) return [3 /break/, 2];
will result in not(false) = true when a user is populated which will return [3 /break/, 2] therefore leaving the user blank when saved.

I changed the line to this
if (newValue[0].id === undefined || parseInt(newValue[0].id, 10).toString() === "NaN") return [3 /break/, 2];
which resolved the issue and now the user is saved.

Steps to Reproduce

1. Make sure your list has a User field for one person only.
2. Create a SPFx Form Customizer extension solution using REACT.
3. Install @pnp/spfx-controls-react
4. Use the DynamicForm control and use fieldOverrides to create your own PeoplePicker control (personSelectionLimit=1).
5. Deploy or run in workbench and enter a user and click Save. The form will save but the User field will be blank.
