bug(Datepicker): setting value inside valueChanges doesn't update the UI

[dana-c0914]

Is this a regression?

I don't know if this was working at some point or not

Description

I am using reactive forms to get/set values from a datepicker and I noticed that if I set a date manually, inside the valueChanges event based on some condition, the value of the form control updates, but not the UI.

The UI changes however if you remove the input and manually set a value inside valueChanges.

Reproduction

StackBlitz link: https://stackblitz.com/edit/qpu5ns Steps to reproduce (1): (1*. Select any date - optional)

1. Select the 10th of any month
2. Check date displayed in input vs date printed under the input

Expected Behavior

We have the same date in the input as printed below the input

Actual Behavior

The date in the input is the date selected using the datepicker, the date below the input is the date set inside valueChanges

Confirmed, as a workaround you can wrap your setValue call in a Promise.resolve(): https://stackblitz.com/edit/qpu5ns-pb413w?file=src%2Fexample%2Fdatepicker-api-example.ts
