I created a tablist that uses a table for items in the list. In this case there many items in that list. As in dozens, not hundreds or thousands.
I've set up an icon to search ascending or descending. In any case, the tablist shows 16 tabs, and then 3 dots. If I'm looking for something not displayed and click the three dots, I get a vertical list with another 17 available items. There are probably another 80 or so missing. If I invert sorting I get the other end of the item list, but the same issue. I can get round this issue using a search box, but is there any way to know why this happens? I expected to be able to move over to the right, or get that vertical list and scroll the list.
Here are a couple screen shots showing the opposite ends of the list
