Timepicker component with no value set has its popup after opening scrolled to minimal value, eg. 00:00.
Requested behavior would be that the component allows to set value to which should the popup be scrolled after opening, when the component has no value set.
When user e.g. records his work hours, in most cases his work starts at the morning or at the current time. With current behavior the user needs to scroll every time to value he needs to set.
