Bug report - Cartographer quest and instance queues

While doing the cartographer quest on Isle of Dorn my dungeon queue came up.

I accepted and completed the dungeon. When I left the dungeon instead of being on the island I was stuck in mid-air somewhere off the map of Hallowfall.

To get unstuck I joined a follower dungeon and then used my hearth to get out of the loop.

The unstuck character service was not clickable while I was stuck in the air.

I was able to recreate the issue again by starting the cartographer quest and then queueing for a follower dungeon.
