Gérard, are you aware that Opera 9.5 (or around this release) and 
earlier would parse this test wrong.


I even have this noted in my CSS elsewhere.

/* dangerous hack - style for Opera 9.5 since it incorrectly parses 
hsla background color even thought it doesn't support the property.

*:not(:first-child)~html #wrapper2+div h3+ul li:hover {background: #9fe}
*:not(:first-child)~html #wrapper2+div>div {background: #afc}

NOTE, do demo for this bug 


For the first demo, the 2nd test has a test for multiple backgrounds.


Just testing this with Opera 9.26. The 2nd test shows two backgrounds.

So why do different test of multiple backgrounds show different results?
