In ISO I'm hitting the export to HTML button, and seeing stylesheet element for the googlefont showing up in the rendered output.

In the source, I see it's getting html encoded.

meta name="generator" content="Compositor Iso"/><link rel='stylesheet' href='https://fonts.googleapis.com/css?family=PT+Serif'>

Everything else is fine, just that element.
