Xinha: internal link to gif is not stored correctly using IE9

When adding any gif (not only animated) that is available in the Images section in the cms to a rich text field using IE9, the link is stored in the rich text in a different way than normal. It does show up in the rich text itself, but not in the site.

Linking to a gif using chrome results in:
<img src="animated2.gif/{_document}/hippogallery:original"/> in the hippostd:html node. Below that node a child node is created with the uuid to the image. HST can handle that and knows how to create the correct image src.

Linking to a gif using IE9 results in:
<img src="binaries/content/gallery/standaardsites/hobosa/animatedgif.gif/animatedgif.gif/hippogallery:original"/>. The child node below the hippostd:html node is not added. HST does not know how to create the correct link now. WARN [org.hippoecm.hst.content.rewriter.impl.SimpleContentRewriter.rewrite():186] Could not translate image src. Skip src
