DatePicker with Enable24hours does not apply minutes on change

[ralfbalzer]

I am using the DatePicker with Enable24hours set to "true".
When I change the hour on the dropdown calender and I press TAB, the cursor moves to the minute field and applies the hour in the input field .
However, if I press TAB after entering a value in the minute field, the minutes are not applied.
I have to either use SHIFT + TAB or click somewhere else in the control to apply the value.
Ideally after entering the minute value, I would press enter to close the dropdown calender but if I do that, the minute value is never updated.
