Sticky Nav Header transition is jarring

[Myke623]

When the nav transitions into the sticky state, the selected tab transforms to display a drop-down arrow containing the (now hidden) sub-tab elements. After the transition, all of the following tab items are offset to the right, making the transition from normal to sticky state visually jarring.



Perhaps ensuring that the width of the selected tab is the same during normal display as it is when sticky can prevent this from happening.
