Thanks for the feedback, the transitions here are as designed for now though and it's expected that holding starts the focus transition for the button but activating (releasing the mouse button) actually transitions to the newly selected area.
Nothing extracted yet.
When using the keyboard to navigate between the Store Library and Community tabs the animations look smooth and help you to see what's happening. But when you use the mouse the animation is not smooth, and it makes it hard to see what is going on because it happens so fast.
A simpler animation for switching to the next/previous view once they are already open would make it easier to see what is happening.
As a side note to this issue: If you click and hold the buttons they do the same animation as when you press the up arrow to select the three main buttons, which really is not needed and is what is causing the issue above, hoever if you click and drag the the mouse out of the button then the animation does not plan back but remains in the state as if you have hit the up arrow. You can use the keys to navagate between the three buttons as if you had hit the up arrow, but they remain at the top of the screen instead of the middle of the screen:
