Is it possible to run a WebGL build on Android by loading it from localhost in a WebView?

I want to use the same WebGL build across all platforms, but when I host it on an actual web server and load it in an Android WebView, the framerate drops significantly. I’m aware part of it might be due to WebView limitations, but I’d like to test it locally to see if that improves performance. Is there a good way to do this?
