Component icons are missing for SRP components (Lens Flare SRP, URP Decal Projector) when searching in the Add Component menu

Steps to reproduce:

1. Create a new project using Universal 3D template
2. In the Hierarchy, add an empty GameObject
3. In the Inspector, click "Add Component"
4. Type in "Lens Flare (SRP)"
5. Observe the search result

Actual results: "Lens Flare (SRP)" is missing an icon next to it in the search results

Expected results: "Lens Flare (SRP)" displays its assigned component icon in the Add Component menu search results

Reproducible with versions: 6000.5.0b2 (4427344da5e9), 6000.6.0a2

Not reproducible with versions: 6000.4.1f1, 6000.5.0b1 (c1f81ff5b082)

Tested on (OS): Ubuntu 24.04, macOS 26.3

Notes:

• This issue also reproduces when searching for the "URP Decal Projector" component
• The icons display correctly on the component headers in the Inspector once added, but are missing entirely from the search dropdown
