Favicon indicator is not working correctly in Chrome on Mac
Hi, I'm using a Drupal module (Environment Indicator) that uses the TinyCon library. The favicon function does not seem to be working correctly in Chrome.
There is a little "T" next to a square color, instead of overlaying. See image.

This works fine in every other browser. It also worked fine in Chrome on my local computer. I can't tell what changed. Perhaps I updated the image and that caused it to stop working? Is there a specific file format, dimensions, file size, etc. that are required for it work right in Chrome?
I tried the change in a previous issue #96, but it made no difference. I have also closed my browser and flushed my cache.
Thanks.
To clarify, it works fine in Windows. I think it's an issue with Macs.
Also, I made sure that only a standard favicon.ico file shows up in the HTML, and the issue still occurs, so I don't think it has to do with the file format, but something else.
FWIW, in case anyone else has this issue, I was able to resolve this by rolling back the TinyCon.js file to v0.5. The issue may be with the latest update.
