Some Declarative examples and demos don't work well with virtual keyboards

Go trough declarative examples and demos, test and fix input panel support:

• application sets focus to editable TextInput inside a element with opacity 0 (but visible true) or inside a element that is off screen, causing it to have input focus and open virtual keyboard on devices where input panel follows focus
• dialogs with TextInput closing on click, when click is needed to open input panel on some devices
• sets focus to inputs when opening a view where the text input is not the first/primary action user would likely want to take
