URP RenderGraph RenderPass doesn't clear textures

Steps to reproduce:

1. Open the attached project.
2. Build and Run a Web Player build
3.  

Actual results: 
In the web build, the display of the MRT texture is rendering on top of previous frames, smearing the results.

Expected results: 

Like in the editor or other graphics APIs, the render pass texture should be cleared when it's requested, preventing the previous frame smearing that WebGPU is getting.
