Selected time to center

[dzero1]

Hi again,

Here I made another update for the selected time. I fixed the selected time css by adding a "ui-state-active" class and fix the scroll position of the selected time element to center to the pane. Also fixing the _hasScroll function.

You can check the behaviour from following codesandbox.io test url https://codesandbox.io/s/timepicker-test-x7dym
