Build Analysis Build Steps foldouts don't preserve their expanded status when switching between builds

Steps to reproduce:

1. Create a new 3D URP Template project
2. Build the project twice
3. Open the Build Analysis window (Window -> Analysis -> Build Analysis)
4. Select one of the builds
5. In the Build steps, expand some of the Build steps foldouts
6. Select another build report
7. Observe the Build steps foldouts

Actual results: Build Steps foldouts reset their expanded state after switching to another build report

Expected results: Build Steps foldouts retain their status after switching build reports

Reproducible with versions: 6000.6.0a5, 6000.6.0b2, 6000.7.0a1

Can’t test with versions: 6000.6.0a4 (Build Analysis window not present)

Tested on (OS): Ubuntu 24, macOS 26.5.1
