Bug
If you win dragon, you go to the portal, the next you can see title, but
if you return to the end and jump in to the poratl agan, you can't see the titles
How Check?
create world
/set block ~ ~ ~ end_portal
/kill @e[type=ender_dragon]
go to the portal
set block ~ ~ ~ end_portal (agan)
go to the portal (agan)
and you can't see nothing
(sorry for my English)
That's not a bug it's a feature that was implemented to not annoy the player with the credits every time they exit the end
