So... ( Bear with me a bit )
A couple of days ago, my browsers stopped rendering the {{resolved}} template properly. The image was showing broken.
Eventually got around to tracking it down, found File:Yes-check.svg which only exists on Commons now. It was broken when I went to view it, all the small versions were displaying broken image icon instead of the checkmark.
I went and clicked on the raw file itself, and it rendered properly, full sized. After doing that, it was rendering properly at all scales on all pages.
I don't know if this is a bug in Chrome, a cache bug in the WMF servers, a rendering bug in the SVG stuff, or what. But I thought it was wierd enough to report and see if it was just me, or something wider.
