UIDropDownMenu_AddButton not working as intended

I was debugging the ‘Postal’ addon in Wow Classic Era. There is a method that it calls in the lua called UIDropDownMenu_AddButton which I believe is part of the WoW API. It seems to work fine when you add to level’s 1 and 2 of this method (the second parameter), but no matter how many items you will add to level 3, it will artificially limit the number of items in a level 3 dropdown to 8 items. Can someone look into fixing this? I’m guessing this is a mistake.

Would hate for this to get lost. Hopefully someone will fix it.

This is still a bug…
