Actual behavior:

User uses down key or mouse scroll to change the time. A 00:00 hour is set instead of chosen hour on blur.

Expected behavior:

A value chosen by user remains selected. It's not changed by the timepicker.

Additional Context:

This problem occurs only when picker.enable(true) is called after component creation and user uses down arrow / mouse scroll to get to the the 'previous' day. When no .enable method is called everything works fine. Please see attached code snippets and gifs.

Bug can be reproduced using the following code snippet:

 $(document).ready(function () {
    // create TimePicker from input HTML element
    var picker = $("#timepicker").kendoTimePicker({
            dateInput: true,
            format: 'HH:mm'
        }).data('kendoTimePicker');
    picker.enable(true)
});

Removing 

picker.enable(true)

fixes the issue
