SVG added with data on Slide Master causes file corruption

[rnoelle]

Adding an image to a slide with SVG in base64 works great, but I can't add an image this way to a slide master without receiving an error when I open the file -
PowerPoint found a problem with content in Executive Deck.pptx.
PowerPoint can attempt to repair the presentation.

pptx.defineSlideMaster({ title: 'MASTER_SLIDE', objects: [ { "image" : {x: .83, y: 1.6, w: 5.57, h: 1, data: svgBase64}}], })

The file does open, and I don't see anything actually removed, but with multiple masters it's causing the PowerPoint to save multiple times for every pptx.save()
