### Re: Testing

FYI - I'm using FF on Windows and the square root symbol looks fine to me, that is to say, on my FF, the image in your original post just above this one looks the same as you show for "Chrome rendering".

### Re: Testing

Same here with FF 81 on Android, I don't see any difference in the rendering between FF and Chrome.
