Missing texture placeholder briefly flashes on world icon when returning from Edit screen

When returning from the world edit screen back to the main world selection menu, a missing texture placeholder (the purple and black checkerboard texture) briefly flashes on all world icons.

Steps to reproduce:

1. Open Minecraft and go to the singleplayer world list

2. Click on the “Edit” button for any world.

3. Click “Cancel”

4. Observe the world icons

Expected result:

The world icons should remain stable without displaying any missing texture placeholder.

Actual result:

A missing texture placeholder flashes briefly on the world icons before the correct image loads.
