iOS input focus issues

I am currently having trouble with focus on my inputs for iOS. It works perfectly on Android, but for some reason something is going with iOS where sometimes it takes multiple clicks before it actually registers a click event on the input and opens the keyboard with focus in the input and other times it gives focus to some random element behind the visible one so the keyboard opens, but the input field doesn’t have focus. We have multiple inputs that are hidden behind the visible one, but I don’t think that should matter.

I have figured out the solution and to make it work better. Instead of having all the inputs within the footer, I add and remove them every time. That way there is only ever one input within the footer. This seems to work fairly well. The second thing I did was to handle the phantom keyboard case by add the following code.

window.addEventListener('native.keyboardshow', function(){
  if (document.activeElement.nodeName !== "INPUT") {
    var activeElement = document.querySelector("#chat_footer_inputs input");
    if (activeElement) {
