Error in DOM insertion

Getting an error in the editor for DOM insertions when attempting to add google maps js api call. error thrown is “named entity expected. Got None”. the code is:

is this a bug?

<script type="text/javascript" src=""></script>

It is and it isn’t. I see this too, the script tag is fine but the parser that checks the code see’s something within the API key and trips that. It should work fine though.
