jQuery 1.3.2の NS_ERROR_XPC_BAD_CONVERT_JSの件

• resolution set to invalid

In order to get the offset the element must be visible. Either the offset method must do some detection work to figure out if it is hidden, then show it, and finally hide it... or the developer can just call .show().offset() and then .hide(). The overhead associated with putting the logic inside offset/position isn't justifiable in an already expensive operation.

It is better to show the error than to hide it and give some odd result that is unexpected.

ということはバグじゃなくて正しくない使い方ということか。
