Fix iOS resizing bug

On iOS devices (iPhone, iPad), you only need to include the meta viewport tag for it to initially load properly. But if you rotate the device after loading, it will resize and be slightly too zoomed in. The code below fixes this.

* Enqueue iOS bug fix
function be_enqueue_ios_bug_fix() {
wp_enqueue_script( 'be-ios-bug', get_stylesheet_directory_uri() . '/lib/js/ios-bug.js' );
add_action( 'wp_enqueue_scripts', 'be_enqueue_ios_bug_fix' );

(function(doc) {
var addEvent = 'addEventListener',
type = 'gesturestart',
qsa = 'querySelectorAll',
scales = [1, 1],
meta = qsa in doc ? doc[qsa]('meta[name=viewport]') : [];
function fix() {
meta.content = 'width=device-width,minimum-scale=' + scales[0] + ',maximum-scale=' + scales[1];
doc.removeEventListener(type, fix, true);
if ((meta = meta[meta.length - 1]) && addEvent in doc) {
scales = [.25, 1.6];
doc[addEvent](type, fix, true);
