Thank you for reporting a bug to Unity. After reviewing the behavior, we've confirmed it aligns with the current design and intended use of the feature. We understand this may differ from your expectations or workflow. We will close this case as 'As Designed.' If you have feedback on how the feature could better meet your needs, please let us know - we value your input and consider it in future improvements.

Steps to reproduce:
1. Create new Unity project
2. In Project window create TSS Theme File asset (Create > UI Toolkit > TSS Theme File)
3. In Inspector window > Style Sheets list press “+”
4. Select “NewTSSFile”
5. Press “Apply” button

Actual results: “Assets/NewTSSFile.tss: warning: Circular @import dependencies detected. All @import directives will be ignored for this StyleSheet.” warning is thrown in the Console window
Expected results: Inspector should prevent assigning TSS Theme File to it’s own Style Sheets list or doesn’t allow selecting TSS Theme File for the list

Reproducible with versions: 6000.0.71f1, 6000.3.11f1, 6000.4.1f1, 6000.5.0a9, 6000.6.0a1

Tested on (OS): macOS Silicon Tahoe 26.3.1 (M1), Ubuntu 24.04
