I'm editing a Calibre-generated EPUB 3 file. The cover page is perfectly ordinary: <body>
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1" viewBox="0 0 573 862" preserveAspectRatio="xMidYMid meet" width="100%" height="100%">
<image width="573" height="862" xlink:href="cover.png"/>
</svg>
</body> ADE shows it as a tiny thumbnail, the same kind as displayed in the library. Other random ebooks work fine with the same code and image. I converted with Calibre one such book from EPUB 2 to 3 and reproduced the problem. Any idea what's going on? The code seems the same.
