Dan Caseley commented on CB-5115:
---------------------------------

Info for future people: We hit a similar problem, characterised by the tapped input field ending up under the keyboard after the tap & auto-scroll. We found this resolved by iOS 7.1.

>    Affects Versions: 3.1.0

> On iOS 7, when a Cordova 3.1 app contains input fields (<input>, <textarea>), the events such as "focus" and "click" can be dispatched to the wrong element when taping the field causes the virtual keyboard to show up.
> Apparently, the event dispatching mechanism is confused by the fact the page is pushed by the keyboard showing up: the events are dispatched to the element at the coordinate after the push, instead of the element at the coordinate of the initial tap gesture.
> Reproduced with Cordova 3.1 using Xcode 5.0 on Mac OS X 10.8.5, running on iPhone and iPad simulators and real devices. 
> How to reproduce:
> Run on iOS 7 a Cordova 3.1 app using the code from the attached test file. The test contains several input elements, and a message area which displays a message for each "focus" and "click" events received by the input elements; the message includes the id of the element. When tapping an input element while the keyboard is not visible, the message shows that the event is received by wrong element. Also, the wrong input is focused. Differently, when the keyboard is already visible, the events are dispatched to the correct element.
> Notes:
> - Reproduced only when *not* using height:device-height in the meta tag, per the recommendation in the Cordova 3.1 doc (http://cordova.apache.org/docs/en/3.1.0/guide_platforms_ios_upgrading.md.html#Upgrading%20iOS).
> - Setting KeyboardShrinksView to either true or false in config.xml does not matter for this issue.
> - The same test code works fine in a pure webapp in Safari on iOS 7.
