Teleporting into ungenerated chunk doesn't display biome information for new chunk until debug screen is reopened ("Waiting for chunk")

Can confirm; however, closing the debug screen then opening it again will display the biome.

It should not be necessary for the player to force the display of the chunk information manually. That's not a fix, it's a workaround. Refreshing the chunk information should happen automatically. It happens automatically in other circumstances, eg: when determining the regional difficulty, which is initially displayed briefly as if the chunk is zero-age.

Teleporting is not always a one-shot. Sometimes teleporting can happen repeatedly in a loop. This is a common technique for pregenerating chunks.
