This packing behavior is intended, when packing exceeds more than 1 page, subsequent sprites are packed such that the last page is tried first (as this is created anyway) to the first to ensure 1. Faster packing, it does not have to check the mostly full first page each time for available space 2. Uniform distribution.

Reproduction steps:
1. Open the attached “Test VP8.zip“ project
2. Select 4096 as Max Texture Size in “UI Atlas” Sprite Atlas
3. Press the “Pack Preview” button and observe the generated Preview window

Expected result: All textures that could be fit into the selected Max Texture Size are rendered in the Preview window
Actual result: Some textures that could be fit into the selected Max Texture Size are not rendered in the Preview window

Reproducible with: 2021.3.34f1, 2022.3.17f1, 2023.2.6f1, 2023.3.0b3

Reproduced on: Windows 11 Pro, macOS Sonoma 14.1.1 (Intel)
Not reproduced on: No other environment tested
