Value change event with userOriginated true is sent when a DateTime is truncated

In Vaadin 8.11, when you fill a DateTimeField with a LocaleDateTime a event is sent with userOriginated=true.

The behavior is not expected as the user didn't do any changes.

Here is the code to reproduce it:

        DateTimeField date = new DateTimeField("Date");
        date.setResolution(DateTimeResolution.SECOND);
        // don't throw value change listener
        //date.setValue(LocalDateTime.now().truncatedTo(ChronoUnit.SECONDS));
        // will throw a value change listener
        date.setValue(LocalDateTime.now());

        System.out.println(date.getValue());

        date.addValueChangeListener(event -> {
            if (event.isUserOriginated()) {
                System.out.println("From user " + event.getValue());
            } else {
                System.out.println("NOT From user " + event.getValue());
            }
        });

To avoid this value change event, you can truncate the value with the same resolution (here in second).

Start by reproducing the behavior with the DateTimeField snippet, using a value whose precision exceeds the configured SECOND resolution. Then inspect the DateTimeField value-change handling; done means truncation during programmatic setValue does not produce a value-change event marked userOriginated=true.
