Out of the box, the demo is responsive, Ctrl-F search works, zooming in and out of the browser works, my browser scroll settings and keyboard shortcuts are supported, I can load custom fonts through browser extensions. It's not perfect -- buttons are just divs, and there are a lot of divs. But I was expecting that this would just be a shim around Canvas designed to preserve a few old projects; I didn't expect the authors to have put the effort in that they did to do this correctly.
Getting cross-platform WASM toolkits to render to real HTML has kind of been my personal hill to die on recently, so it's just a pleasant, happy surprise to load up a cross-platform app and not immediately get a bunch of errors about how I need to enable WebGL to look at it. If OP or anyone else around had anything to do with the project itself, I just wanted to say that I noticed, and thank you for your care and attention to that detail.
