Ender pearls do not retain effect when leaving and rejoining a world.

In previous versions of the game, if you threw an Ender Pearl and left a world or server, then rejoined before the Ender Pearl hit a surface, you would teleport once it did. But in newer versions of the game, this is no longer the case. Ender Pearl physics were changed a while back so I can only guess that this change somehow effected how Ender Pearls save data, causing the issue.
