Can you post a link to your test site?
OR post a "working page" - starts with
<!doctype html>, includes the
<head> section with CSS or links that work for us, the
<body> section and relevant HTML code, and finally ends with
</html>. Be sure to include any files or images that are called, especially foreground images whose width and height attributes are not included or do not reflect the actual dimensions of the images.
I'm not intimately familiar with SVGs so I need to see some working code to understand why the name of the .pdf file is showing in the black space at the top of the screenshot and how or if that might be changed.
