Effects: removeClass without parameters does not remove all classes

[MichaelM]

Hello,

I'm using jQuery 1.9.0 and UI 1.9.2, and found that the combination of the two causes removeClass() without any parameters to pass an argument length of 1, causing it to not remove any classes. I managed to fix it by changing a line in my jQuery file, but that's just a temporary hot fix for my application.

Example of empty removeClass() with jQuery UI: ​http://jsfiddle.net/nbyCC/3/

Example of empty removeClass() without jQuery UI: ​http://jsfiddle.net/nbyCC/4/

The line I modified:

proceed = arguments.length === 0 || typeof value === "string" && value;
                               ^

to

proceed = arguments.length === 1 || typeof value === "string" && value;
                               ^

Though I see this as an ugly fix.

Verified. When jQuery's docs a call to removeClass with no parameters should remove all classes. When jQuery UI is included this does not happen ​http://jsfiddle.net/tj_vantoll/KyRMY/.
