- Chrome - Requesting twice.
- In Network Tab, Initiator says "Parser".
- Message in consoleResource interpreted as Image but transferred with MIME type text/html: "http://pageurl"
- Firefox - No messages, but it is requesting twice.
- Fidder - Not requesting twice.
- When use Fidder to see Chrome and Firefox's requests, the second request head contains:Accept: image/webp,/;q=0.8
Cause: background-image: url
Don't have much to say here, not sure if it's a bug or not.
