[Addressables] Editor performance drops significantly when rendering Addressables group in Inspector that contains a large number of assets
How to reproduce:
1. Open the “IN-122145_AddressablesPerformanceBug“ project
2. Open Window > Asset Management > Addressables > Groups
3. Expand and highlight “Group 4”
4. Scroll through the Addressable list
Expected result: No change in performance
Actual result: Editor performance suffers, scrolling is slow
Reproducible with: 2.2.2 (6000.0.40f1), 2.7.4 (6000.0.60f1, 6000.2.10f1, 6000.3.0b7, 6000.4.0a3)
Reproducible on: macOS Tahoe 26.0.1, Windows 11 (by reporter)
Not reproducible on: no other environments tested
Note: Selecting any other addressable asset or closing the Inspector window fixes the issue

Resolution Note:
Firstly; thank you for reporting this issue, it inspired some interesting discussions.
Having looked into it, the issue is caused by the Addressables packages use of IMGUI (which is heavy!).
We do have plans to migrate the Addressables windows to UIToolkit, but we'll complete that work outside of a bug-fix - it's quite a large undertaking!
