Custom JavaScript Under Misc Settings Problem

Good Day!

I am trying to add the web site satisfaction survey JavaScript script from Google Surveys. I was trying to use the Custom JavaScript box under Miscellaneous Settings (Mantra 2.0.6). I place the code in there:

<script async="" defer="" src="//survey.g.doubleclick.net/async_survey?site=xxxxxxxxxx"></script>

and do a save. Problem is that it does not remain there and does not go into the code. I noticed in the help bubble, you state that script tags are not needed. That is a true statement if you are placing an inline script (I tested that and it works fine). Problem is that to include a script by reference (i.e. src=), Mantra strips the script tags leaving nothing.

I am looking through the code to see if there is a quick fix – I dread adding something hard-coded because it gets lost with updates. Any thoughts?

Thanks for the super theme – I am having a hackers field day mod’ing using the Theme Settings!
