GoogleWebFont subset does not work in IE

[KostaStolbunsky]

Support Hash

Steps to reproduce

Choose Arimo Google web font and set Hebrew subset
https://www.screencast.com/t/GmYl5JL5CP

Actual Behavior

In browser source code it looks as follows
<link href="http://fonts.googleapis.com/css?family=Arimo:400,700&amp;subset=hebrew" rel="stylesheet">

Expected Behavior

While Chrome, Safari and Firefox interpret & sign as expected, Internet Explorer (including Edge and below) does not recognise it and as a result a subset does not loaded.

Any Error Details (PHP/JavaScript)

In file ReduxCore/inc/fields/typography/field_typography.php
Lines 612, 654
$link .= "&subset=" . implode( ',', $subsets );

Changed & to & as a dirty workaround and now subset is loaded in IE as well
