Onion images are not displayed

When viewing http://expyuzz4wqqyqhjn.onion/images/icon-TorBrowser.jpg the image isn't displayed at all - the previous or empty page remains in the tab, but the context menu stops working.

This is only for onions; the corresponding https://www.torproject.org/images/icon-TorBrowser.jpg (with the centering restriction of legacy/trac#26544 (moved)).
