Expected / Desired Behavior / Question

Added validation function to onGetErrorMessage property of a PropertyFieldPeoplePicker field. Wrote the validation function to fail on purpose and expected to see error message in property pane under the people picker field.

Observed Behavior

No error message was displayed.

Notes:

1. Specifically, it looks like there is an issue on line 162 of PropertyFieldPeoplePickerHost.tsx where the error message logic is only run if the result is 'undefined'.
2. I updated that line locally to see what the error message would look like and observed that the css was not rendering as expected. The people picker did not have a red outline and the error message was not displayed in red text.
