Steps to reproduce:

I have an Angular app and I tried to change a date through the native datepicker.

Actual results:

Angular relies on the input event ( Because there is no input event, the value of the FormControl is not updated. Form validation fails and of course the value is always null (or whatever the initial value was).

Expected results:

The input event should be emitted so that frameworks like Angular or Reac get notified about the new value.
This bug is very similar to bug #1267638 and the same test from there can be used here. The test case shows that there is no input event when using Fennec but when using Desktop (with dom.forms.datetime enabled of course). Also, Fennec emits the input event for other input types but not for date, datetime-local and month (I guess for all input that use the datepicker of Fennec).

Right now, it requires a workaround such as the one posted at or a custom ControlValueAccessor that listens to the change event as well.

Interesting coincidence with bug 1386990 there - in any case I can confirm this and we should fix it.

Is this something we should nominate for uplift to Beta or can it ride the 57 train?
