Sometimes, Chrome incorrectly formats the second button and just applies swatch B to the whole lot. The behaviour seems to occur as follows:
- In a standard Chrome window, the formatting is correct perhaps 50% of the time - if it's not formatted properly, a page refresh seems to correct it
- In an Icognito window, the formatting is applied correctly every time
- In a chromeless window (from the Tools > Create application shortcuts... feature), it almost never formats correctly - you have to refresh perhaps 20 times before it formats properly
- In Firefox it works without any issues
The fact that it works in Incognito mode makes me think there is some sort of caching issue, but this one has me stumped - any ideas?
