Dropdown update problem with an undefined value

[Thomas FRITSCH]

Hi,

We have a problem with the dropdownList component.
We are using it with a reactive form.
When we initialise the form with values, and change the select value to "undefined", it doesn't refresh and always displays the old value (like in the video).
With null this works correctly.

I've made a demonstration project and a video to show you the problem.

Project example : https://stackblitz.com/edit/angular-gesr3c

Can you correct this problem?

Thank you very much.
