The image data in the data uri scheme decodes to images from VectorBeta [3] like: VectorBeta/resources/typography/images/search-fade.png VectorBeta/resources/typography/images/tab-break.png VectorBeta/resources/typography/images/tab-current-fade.png VectorBeta/resources/typography/images/portal-break.png
