Web demo gallery crashing on Chrome (Linux)

I noticed that the ["Try the web demo gallery"](https://emilk.github.io/egui_plot/) is currently not working as expected. When running it in a browser, the app displays the following error: `The app has crashed. See the developer console for details.`

**Environment:**

* OS: Ubuntu 24.04.4 LTS
* Browser: Chrome Version 146.0.7680.164 (Official Build) (64-bit)

**Console output:**

```
panicked at demo/src/main.rs:57:21:
Failed to start eframe: JsValue("No suitable graphics adapter found; noop not requested, vulkan support not compiled in, metal support not compiled in, dx12 support not compiled in, gl support not compiled in, webgpu not requested")
```

**chrome://gpu/ output:**

```

While the demo works with vulkan enabled, this isn't a viable workaround as vulkan is experimental, breaks all video playback, and causes other issues.
