WebGL2 examples not loading on IPhone

## Relevant system information
* IPhone 16e
* Chrome
* Haven't checked logs but doesn't load on Safari either.

## What you did

I was testing bevy on my different devices due to needing to use it in my upcoming projects and noticed on my iphone 16e that none of the examples load whatsoever.
I simply loaded one of the examples and noticed the lack of loading regardless of duration waited so I tried another and another and well I can repeat myself many times on; the examples simply remained blank with their highlight border around them.

## What went wrong

None of the examples loaded (note: wasm and webgl is fully supported on the device and the software)

I very am sorry about the formatting; grabbing the log on chrome on iphone is awkward and it doesn't cleanly copy and paste but is still readable to recognize the clear panic from the winit crate.

Start by reproducing a WebGL2 example from bevy-webgl2-examples.pages.dev on an iPhone 16e in Chrome and Safari, using the browser log in the issue. Trace the reported panic at winit-0.30.12/src/platform_impl/web/event_loop/window_target.rs:582:26 and the generated wasm_example.js stack. Done means the examples load without this panic on the affected device.
