I have repurposed this demo to tinker with accessibility options in MathQuill type. Current test is a sans-serif font called Noto Sans Math applied to every character in the math field, with variables remaining italicized. Initially this page was for creating and testing the virtual keyboard.

This is an editable span, but no MathQuill. I'm pretty sure it wraps when I write too much in it.

LaTeX of what you typed:
