$(element).is(':visible') should return true if either offsetHeight:0 or offsetWidth:0?

Description

Hi there,

At present, $(element).is(':visible') returns true _only_ if element.offsetHeight and offsetWidth are _both_ 0px.

Surely $(element).is(':visible') should be true if _either_ element.offsetHeight or offsetWidth is 0px? Isn't 0px * anything-px = 0px-squared, so element cannot be visible?

Example html follows: please check the console. Tested in Mac FF8.01 and Safari 5.1.1.

Thanks.

Pete.

            console.log('offsetWidth: ' + element.offsetWidth);

Sounds great. Can you test with IE6/7/8 on elements including table rows and columns that are empty? That is what I believe resulted in the current code. Once you have those test cases we can consider a change.

Sure. I'll try to get the other test cases done next week.
