memoryprofiler parent div doesn't have a class

[Hemaolle]

Emscripten 2.0.19.6-unity
(Using Unity 2022.3.7f1)

The HTML generated by using --memoryprofiler option doesn't have a class for the parent div. This would be good to have to be able to set up some CSS to bring the memory profiler UI in front of my app that is running in full screen.

Makes sense to me. Feel free to send a patch if you have time.
