Header bar and footer bars get hidden with ios keyboard

I am trying to add a save button that always shows on screen regardless of whether the keyboard is showing or not. I have tried putting the button in both an ion-footer-bar and an ion-footer-bar. Both of these show up when the android keyboard is showing but when the ios keyboard shows the buttons are not seen. It seems like there might be a fix in cordova using keyboard-attach, but we have a web-app so we can’t use cordova. Is there any solution for those using a web-app?
