VFX Template Uncategorized Category does not auto expand when Last Used sorting is used

Steps to reproduce:

1. Open the attached project
2. Create a new VFX asset in the Project window
3. In the VFX Template window, use the "No_Cat" template from the Uncategorized group
4. Reopen the VFX Template window
5. Set the sorting to Last Used (If not already present)
6. Collapse all categories
7. Close and reopen the VFX Template window

Actual results: The Uncategorized category remains collapsed ("No_Cat" template is selected correctly, however)

Expected results: The Uncategorized category is auto-expanded if it contains the last used template. This is the current behaviour of other categories

Reproducible with versions: 6000.5.0a8, 6000.5.0b5, 6000.6.0a3

Can’t test with versions: 6000.0.73f1, 6000.3.14f1, 6000.4.4f1, 6000.5.0a7 (Category auto expand for last used sort was not present)

Tested on (OS): macOS 26.3.1

Notes:

• The issue does not occur with other categories. If the steps were repeated using the "1" Template from the "1" category, auto-expand functions as expected
