Prevent iOS webview from going BACK under status bar - ios

Question

I have a phonegap/cordova app and when I call the ChildBrowser from the app, exit the childbrowser, and go back to app, the webview goes under status bar.
There are a million answers as to how to prevent webview (in iOS7 and later) from going under status bar. That is not the issue here because initially the app is fine and its webview is not overlapping with the status bar.
The issue happens only after exiting the childbrowser.
Basic flow:
Launch app (all is fine) -> call ChildBrowser (from app) -> Exit ChildBrowser -> back to app (PROBLEM: webview under status bar).
Please ask for clarifications and please advise.
