Template window query search shows all available Category names when searching

Steps to reproduce:

1. Create a new Unity project using a High Definition 3D Template
2. Go to Assets > Create > Visual Effects > Visual Effects Graph
3. Select and create any VFX Graph
4. In the Project window duplicate it
5. For each VFX Graph, enable "Use as Template" and give different "Category" names (e.g. "test" and "placeholder" or any two different names)
6. Go to Assets > Create > Visual Effects > Visual Effects Graph
7. Click on the "+" icon in the search bar
8. In the opened menu, type in the name of one of the VFX Graph templates (e.g. "Test")
9. Observe the search result

Actual results: the search result shows all created "Category" names 

Expected results: the search result only shows the results that fit the search query, in this example it should be only "Test" Category

Reproducible with versions: 6000.5.0a5

Can’t test with versions: 6000.0.66f1, 6000.3.5f1, 6000.4.0b5, 6000.5.0a4 (search bar functionality does not exist)

Tested on (OS): macOS 26.2 (M1)

Notes:

• Searching in "Area" or "Operators" filters work as expected
• Also affects Shader Graph template window
