Hi Mike, thanks a lot! Just tested it. It works fine for Chrome and Firefox on Windows 10 and Linux (with dead keys enabled and disabled).
This will be very helpful for my users! Unfortunately, I don't see an improvement for Chrome and Firefox on macOS 10.13. I haven't tested with other browsers, yet.
