When you focus input field on old Android - keyboard does not appear

[mikegordienko-devpronet]

I've the page that uses touchscroll.js and in old Androids after focusing input on the page the keyboard does not appear.
The fix that helped me was to check if the properties are defined in browser

function setTransitionProperty(/HTMLElement/node){
if ('webkitTransformStyle' in document.body.style) {
node.style.webkitTransformStyle = "preserve-3d";
}
if ('webkitTransitionProperty' in document.body.style) {
node.style.webkitTransitionProperty = "-webkit-transform";
}
};
