[TIMOB-3274] iPhone 1.6.0 Grouped TableView scrollable: false still displaces

Using 1.6.0 on an iPhone

I have a grouped tableview in a modal window.
Under 1.5.1 setting scrollable = false on the tableview would fix it in position so when focus is made on one of the textfields in the tableview the tableview wouldn't jump down the page. (See sceenshot1.png). I've just tried the following code on 1.6.0 as it seems like scrollable = false isn't working in the same way it was in 1.5.1 - when focus is made on a textfield the tableview displaces (See screenshot2.png)

This behaviour occurs in the simulator and on the device.

I've also attached a zip of a Resources directory that shows the problem (you need to click on the register button)

var registerData = [];
        
var usernameRow = Titanium.UI.createTableViewRow({className:'defaultRow', hasChild:false, selectedBackgroundColor: 'white', selectionStyle: 'NONE', selectedColor:'white'});

var passwordRow = Titanium.UI.createTableViewRow({className:'defaultRow', hasChild:false, selectedBackgroundColor: 'white', selectionStyle: 'NONE', selectedColor:'white'});

var registerUsername = Titanium.UI.createTextField({
    keyboardType:Titanium.UI.KEYBOARD_EMAIL,
    autocorrect:false,
    hintText:'email address',
    height:29,
    left:10,
    width:285,
    clearButtonMode:Titanium.UI.INPUT_BUTTONMODE_ONFOCUS, 
    autocapitalization: Titanium.UI.TEXT_AUTOCAPITALIZATION_NONE
});

var resgisterPassword = Titanium.UI.createTextField({
    keyboardType:Titanium.UI.KEYBOARD_DEFAULT,
    autocorrect:false,
    hintText:'password',
    height:29,  
    left:10,
    width:285,
    clearButtonMode:Titanium.UI.INPUT_BUTTONMODE_ONFOCUS, 
    autocapitalization: Titanium.UI.TEXT_AUTOCAPITALIZATION_NONE,passwordMask:true
});


usernameRow.add(registerUsername);
passwordRow.add(resgisterPassword);

registerData[0] = Titanium.UI.createTableViewSection();
registerData[0].add(usernameRow);
registerData[0].add(passwordRow);

var registerTable = Titanium.UI.createTableView({
    style:Titanium.UI.iPhone.TableViewStyle.GROUPED,
    scrollable: false,
    data:registerData,
});
