InAppBrowser no focus on input text fields

When opening a webpage with a form in the Cordova default webview or system webview focus on an input text box works as normal - a cursor is displayed (and if there's any js list its displayed). However when using the InAppBrowser the focus cursor does not display at all when you click in a text box...the keyboard comes up but no focus cursor.

I've tried injecting js to focus on the text box but this doesn't do anything..Also it makes no difference what value the option keyboardDisplayRequiresUserAction is given...Is there a fix for this?
