wgpu error when setting Viewport::physical_position value for a Camera

## Bevy version

0.15.0

## \[Optional\] Relevant system information

- Rust 1.81.0
- Windows 11

## What you did

putting Viewport::physical_position value

## What went wrong

I recieved a wgpu error:

ERROR wgpu::backend::wgpu_core: Handling wgpu errors as fatal by default
thread '' panicked at C:\Users\Mohamed\.cargo\registry\src\index.crates.io-6f17d22bba15001f\wgpu-22.1.0\src\backend\wgpu_core.rs:3411:5:
wgpu error: Validation Error

Caused by:
In RenderPass::end
In a set_viewport command
Viewport has invalid rect Rect { x: 150.0, y: 0.0, w: 1600.0, h: 900.0 }; origin and/or size is less than or equal to 0, and/or is not contained in the render target (1600, 900, 1)

No repository file or test is named. Start by reproducing the Bevy 0.15 issue using Camera's Viewport::physical_position and inspect the reported set_viewport rectangle against the render target dimensions; done means the valid viewport behavior is identified and the error no longer occurs.
