Current behavior
https://prnt.sc/uiwip0
Chips float label does not "float" when form value is updated programmatically

Expected behavior
Float label works correctly with Chips

Minimal reproduction of the problem with instructions

1. Create form with Chips control and float label
2. try to update value programmatically like this:
   this.form.patchValue({ cities: ["London", "New York"] });

What is the motivation / use case for changing the behavior?
We want to use float labels with Chips

The same issue with PrimeNg 11. @MaximShchukin did you find the workaround how to fix it?

The workaround would be to add class p-inputwrapper-filled to p-chip element.

This bug is still in master branch. As I understand, the solution is just to add this.updateFilledState() call into writeValue method. Could you fix it, please? Thank you!
