This is an intentional feature: auto-scroll is disabled after
the first time when you scroll the tab-line manually.
Otherwise you won't be able to scroll the tab-line with the
mouse-wheel or using the arrow buttons when auto-scrolling
is still in effect during manual scrolling.
You can reset auto-scrolling by evaluating in e.g. ‘M-:’
(set-window-parameter nil 'tab-line-hscroll nil)
But indeed this is not right way to do this - it should automatically
reset auto-scrolling at some time afterwards after finishing manually
scrolling the tab-line. I was unable to find such a natural event on which
to reset auto-scrolling - there are too many different possible events to
choose from. One of the most natural is to reset auto-scrolling after
manually selecting a tab.
Could you please try this patch to see if it solves your problem:
