Upon entering a dialog while viewing the credits, the background does not reflect the current state of the world

When the player enters a dialog while viewing the credits (only possible in non-singleplayer), the dialog background shows the normal game view rather than the end portal texture. This might be intentional, or too minor an issue to fix… except that the game view is not up to date. Entities do not seem to be shown at all, and blocks appear as they did when the player entered the portal, not as they currently are. Particles still seem to appear and disappear as expected.

This is essentially the same issue as MC-300222 except that the player cannot move freely after the interface is closed.

To reproduce

1. Create a new creative world

2. /execute in minecraft:the_end run teleport @s 0 72 0

3. /kill @n[type=minecraft:ender_dragon]

4. Place an impulse command block near the fountain with the command dialog show @a minecraft:custom_options

5. Make a long line of 4-tick repeaters leading from a button on the edge of the fountain to the command block (see attached video for an example)

6. Use F3+G to show chunk borders, then run /forceload add ~ ~ in all chunks containing redstone-related blocks

7. Place an armor stand near the command block

8. Open the world to LAN

9. Press the button, then quickly look towards the armor stand and command block as you walk into the fountain
   ❌ Observe that, when the dialog appears, although the fountain particles render as expected, the repeaters appear frozen in the state they were in when you entered the portal and the armor stand (and all other entities aside from yourself) are completely invisible (but any nearby mobs are still audible). The fact that you can see yourself in third-person mode, and your arm/held item in first-person mode, may also be a bug since other players cannot see you while you are viewing the credits.

P.S.

Although this issue is very minor, its existence is one more reason to consider refactoring the dialog system so it just appears on top of the credits/chat/in-game UIs, as I suggested in MC-297898
