Steps to reproduce:
1. Unzip the attached user's project "MSAA Bug.zip"
2. Open "SampleScene.unity" and Enter Play Mode
3. Observe white pixels surrounding a mesh with transparent material when the particle system is playing
4. Navigate to "Assets/Settings/URP-HighFidelity-Renderer.asset" and change the Rendering Path to Deferred
5. Enter Play Mode and observe no white pixel artifacts

Expected results: white pixels do not surround a mesh with transparent material when the particle system is playing when Forward or Forward+ Rendering Path is used
Actual results: white pixels surround a mesh with transparent material when the particle system is playing when Forward or Forward+ Rendering Path is used

Reproducible with: URP 12.1.12 (2021.3.31f1), URP 14.0.9 (2022.3.10f1), URP 15.0.6 (2023.1.15f1)
Could not test on 2023.3.0a8 and 2023.2.0b13 due to the particle system and materials no longer rendering

Reproducible on: Windows 11, Windows 10
Not reproducible on: No other environment tested

Notes:
-Issue reproduces in Windows Standalone Build
-Workarounds are: Disabling MSAA, using another anti-aliasing technique, changing the rendering path from Forward+ to Deferred, avoid using materials with Additive Blending Mode
