When dragging the mouse to select the whole input value, only the first segment on the left remains selected after releasing the mouse. The issue is reproducible in the DatePicker demo once you select a date. Video: https://app.screencast.com/Eoa6Xj2MzfOPN.

The problem is only reproducible in Firefox, the whole input is properly selected in Chrome and Edge.

When the user navigates between the views, the DatePicker currently fires a ViewChanged event. This event provides the new view (Decade, Month etc.) but there is no way to detect the selection that the user made in the previous view.

For example, if am in the Decate view, as soon as I select a year, the DatePicker will switch to Month view. The problem that I am facing is that I cannot get the year selected from the Decade view. I need that, so I can display it in my custom HeaderTemplate.
