[MC-214870] "Waiting for chunk..." takes significantly longer since 21w05b

Create a world in 21w05b
Open f3
Observe the biome immediatly

Run

/gamemode spectator
/execute in minecraft:the_nether run tp @s 0 0 0
/execute in minecraft:the_end run tp @s 0 0 0

Biome briefly displays the overworld biome (MC-214871) before correcting to the new dimension.

Create a world in 21w06a
Repeat steps
New "Waiting for chunk..." message appears, and it takes forever to show the biome.

Note: The chunk will load visually while this message displays, it is not a lag issue where the chunk simply is not loading

Moving up or down does nothing, but moving in x or z coordinates cause it to update and display the biome. (in 21w07a)

Fixed in 21w18a???

I do not think so. This issue has always been difficult to track between versions, sometime harder and sometimes easier to notice.

Then that makes me think it might be related to MC-225058. The chunks seem to only be partially loaded when both issues occur, so this might be the underlying cause of MC-225058.

In my experience, closing and opening F3 twice refreshes the chunk information.

Turns out that is a different bug (MC-137814).

May need spectatorsGenerateChunks set to false.
With it true the biome will often update instantly in generated chunks. Would expect it to either not update at all or also instantly, when set to false.

Still in 1.20.4 and 23w51b.

This bug happened since 1.14, not 21w06a.

Close F3 and open it again can make it show normally.

Maybe this issue should rename as" "Waiting for the chunk..." forever shown in Debug screen after teleporting to an unloaded chunk.

How to reproduce:

Create a new world.
run /tp @s ~ ~ ~1000
Don't move out the chunk after teleporting.
The chunks will load normally, but the F3 screen shows"Waiting for the chunk" forever.
