How to reproduce:

1. Open the project “IN-104737_Addressables“
2. Window → Asset Management → Addressables → Groups → Build → New Build → Default Build Script
3. In the Addressables Report, Explore → expand “defaultlocalgroup-…”
4, Observe the Size of “Assets/space-inv-1.jpg”

Expected result: “Assets/space-inv-1.jpg” is about the same size as “Assets/space-inv-2.jpg” (~485B)
Actual result: “Assets/space-inv-1.jpg” is of way larger file size (~176KB)

Reproducible with: 1.21.12 (2022.3.63f1), 1.25.1 (2022.3.63f1), 2.6.0 (6000.0.51f1, 6000.1.8f1, 6000.2.0b6)

Reproducible on: Windows 11
Not reproducible on: No other environment tested

Note: The sprites are not detected as packed, so the original texture isn't stripped and references to it are added to objects that use the sprite
