Mobile Safari Autofocus text field

问题 In Mobile Safari I am unable to focus onto a text field after setting a delay period. I\'m attaching some example code showcasing the issue. If, onclick of the button, you trigger .focus(), everything works as expected. If you hang the focus on a callback, like the setTimeout function, then it fails ONLY in mobile safari. In all other browsers, there is a delay, then the focus occurs. Confusingly, the \"focusin\" event is triggered, even in mobile safari. This (and ~similar~ comments in SO)
