Rerun broken on Emil's iOS Safari and Chrome Android

[emilk]

It worked very recently. Now it is stuck on "Loading" with no error message.

Maybe it's my AdBlocker?

This affects my iPhone 12, iOS 16.4.1 (A).

Niko is on iOS 16.3.1, iPhone 11 Pro, has no problem

No adblocker here, also broken on Android Chrome

This is what I get on my iOS Safari in the dev console:

[Error] panicked at 'wgpu error: Validation Error

Caused by:
    In Device::create_render_pipeline
    Color state [0] is invalid
    Format Rgba8UnormSrgb can't be multisampled

', /home/jp/.cargo/git/checkouts/wgpu-b5b0e12eef369ba9/de497ae/wgpu/src/backend/direct.rs:3019:5

Three things here:

• Panics during startup of web-viewer are not reported to the user #2151
• Why is this broken? When did it break?
• wgpu panicking on errors is extremely annoying (wgpu often panics on errors gfx-rs/wgpu#3777)

get_parameter_i32(glow::MAX_SAMPLES) returns 0 on my iPhone, which wgpu interprets as supporting at most 2x MSAA
