[TIMOB-14255] iOS: TextField keyboard doesn't maintain number/symbol view when in TableView if TextField doesn't have height set

*Problem* On iOS, when you create a Textfield that doesn't have a height set and then add it to a TableView, the keyboard doesn't perform the standard way. When you press the ".?123" key, it shows the number/symbol keyboard view. *Actual result* After pressing one key it goes back automatically to the "ABC" keyboard, which provides for a poor UX when you want to type in multiple numbers. *Expected result* The default behavior is for it to stay in this keyboard view until you press "ABC" to go back to the letters keyboard. *Test case*

var win = Ti.UI.createWindow();

win.add(Ti.UI.createTextField({
	top : 0,
	left : 0,
	right : 0,
	borderStyle : Ti.UI.INPUT_BORDERSTYLE_ROUNDED
}));

var table = Ti.UI.createTableView({
	top : 60,
	left : 0,
	right : 0,
	height : 50
});
var row = Ti.UI.createTableViewRow({
	height : 50
});
row.add(Ti.UI.createTextField({
	top : 0,
	left : 0,
	right : 0,
	borderStyle : Ti.UI.INPUT_BORDERSTYLE_ROUNDED
}));
table.setData([row]);
win.add(table);

win.open();

*Note* Notice that the top textfield, which is not within the tableview, performs correctly. The textfield below that, which is within the tableview, doesn't maintain the ".?123" keyboard as you type. *Workaround* Add a height to the textfield within the tableview and then it will maintain the proper keyboard view.
