WebGL2 Shaders / Storage Buffer Example broken on website

## Bevy version

The one used to make the [bevyengine.org](https://bevyengine.org/) examples

## What you did

Open the [Storage Buffer Example](https://bevyengine.org/examples/shaders/storage-buffer/) set to WebGL2

## What went wrong

Nothing is on screen.

Works fine if I swap to WebGPU
Tried Ctrl F5 to no effect

Reproduce the linked Storage Buffer Example with WebGL2 and inspect the browser console, focusing on the reported wgpu validation panic after the WebGL2 adapter is selected. Trace the example from its website entry point into the Bevy example source; no source file is named in the report. Done means the example renders on WebGL2 without the fatal validation error, while WebGPU continues to work.
