After a the launch of IOS 13, all the buttons on a website that I develop on broke all the buttons. None of the buttons that use Material Design Lite button ripple js effect no longer work. The normal behavior breaks and clicking on a button on the website does not respond with a reliable click event on any IOS device running IOS 13.0+, same with iPad. My company has already contacted Apple for support, which led us here. Link below is an issue opened on MDL's Github explaining exactly what is breaking. https://github.com/google/material-design-lite/issues/5281

I think this is probably about content observation.

I'm also experiencing this issue, in a slightly related case. Elements that have `onclick` bound on them AND an :active psuedo class with issues. The onclick will eventually end up in an unresponsive state, only iOS 13.0+ devices, that forces the User to restart the App (We're using a WKWebView inside of a Native App.
