Gmail's favicon confusion
Gmail currently serves up two possible favicons, a 16x16 shortcut icon and a
32x32 icon. I've no idea why the latter is included, but my browser is happy
to accept either version, which can lead to a rather amusing situation.

Most days when Gmail loads I get the favicon, but I've had a couple of extended periods of seeing the other version instead. I'd even wondered whether Google was undertaking some A/B testing, although this seemed rather far-fetched. I now believe that there's a race condition, and that the smaller image usually wins this race.
I far prefer the 32x32 version (it makes the favicon look anaemic), but when I had a close look at it I was upset by its sloppiness.

Sebastiaan de With would not stand for this!
