strange loss of gpu support when consuming landing page from url other than localhost

[John-Skinner]

I'm using the examples to learn webgpu. One observation is that if i change vite to host on non-localhost via 'vite --host 0.0.0.0', webgpu support is lost when i use the ip url rather than localhost:3000. If i use localhost:3000, then webgpu support is present. Even when the browser is on the same system. I wanted to use this these examples to test webgpu from firefox/chrome running on a few different linux distributions.

I'll look deeper into where there may be any logic that distinguishes localhost in some way.

https is required if not open from localhost Chrome security policy

Thanks lslzl3000. You are right.
