I don't understand why this code block is labelled async defer, but it seems dangerous? AFAIK, async means it's not guaranteed to be run before the inline script block below; but if that happens, OpenSeadragon won't have a definition and the image won't load. Probably most of the time the osd page will be in cache; but it's a big block of code and I've been getting persistent problems in testing with OpenSeadragon not being defined when I run with caching disabled, and I can't think of another reason that would be happening besides async defer here.
Seems like the sort of problem that developers would rarely see, but that might be hitting a bunch of people on their first visit to any given Wax site.
You could pull the defer off too, but that would probably be bad for performance? [edit] And document.onload in jquery should wait for the deferred script to run.
