For people still experiencing this issue, can you please post all details about your system? What operating system are you running, which version, which browser are you using, which version. I can't reproduce this, and without being able to reproduce I can't fix it. I am using Firefox 51.0.1 and Chrome 56.0.2924.87 on MacOS 10.12.3 as well as Chrome 56.0.2924.87 on Android 7.1.1 and all is working for me.
