Autofill doesn't work in iOS using Cordova in-app-browser plugin

I am using the Cordova in-app-browser plug-in to launch a website. I’ve already completed the iOS configuration setup as given below
In iOS after submitting a login form app doesn’t show a save password prompt but it’s working in the mobile safari browser. Also, the Android app working fine.
Does anyone face this problem? Any help would be appreciated.
