Here is the example of the problem: http://jsfiddle.net/wibbletech/gRshU/
The items in the list are relative position divs (its a simple list of font names). The css hover changes the background-color for the items. However, the last item in the list (monospace) only applies the hover setting when mouse is over the top half of that item.
I get this problem on Safari 6.0 (8536.25), Chrome 21.0.1180.79, and Webkit 6.0 (8536.25, 537+). However, Opera 11.66 and Firefox 14.0.1 work fine.
I'm using 2012 MacBook Pro Retina - Mountain Lion.
Can anyone please verify this problem is occurring for them too? Does it look like a bug or am I doing something wrong? Thanks for your help.
