Thanks for the tip! I had `user-select: none` on the container which had the glass inside of it but apparently that didn't work. I just updated the page with `user-select: none` on the glass itself and it looks like that did the job.
It's working great in Chrome and Firefox though.
I was testing on Safari iOS and it looks like the non-prefix version worked there.
