Google API Tracking code missing single quote after account number

[ps202]

Tracking code displayed on website is missing a single code after the account number if Google API has been set through admin backend.

Preconditions

Magento 2.2.0-dev from github

Steps to reproduce

1. Go to: Stores->Configuration->Sales->Google API
2. Enter Account Number
3. Save
   

Expected result

1. Tracking should be working.

Actual result

1. Tracking does not work, single quote missing after account number in code:

<script>
//<![CDATA[
    (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
    (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
    m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
    })(window,document,'script','//www.google-analytics.com/analytics.js','ga');

    
ga('create', 'UA-1xxxxxxxxx1, 'auto');
ga('send', 'pageview');
    
//]]>
</script>

Workaround (LOL): Add single quote after Account number...
