Open all of the provided scripts and make sure the tabs overflow the bar so that the scroll buttons appear.
Make sure the bar is scrolled all the way to the left, then click the grayed out left arrow. Now click the right arrow to scroll right and proceed to click onto a tab, it should then select the tab directly to the left of the intended tab. You can see this in the provided video
It appears as-if it is respecting the click of the disabled scroll button, but only when a new tab is entered. This is just what I’ve observed
