jQuery.map( jQuery() ) does not enumerates all method names.

Description
Test: http://jsfiddle.net/7jSF8/
Documentation:
"Array-like objects, such as jQuery collections, are treated as arrays. In other words, if an object has a .length property and a value on the .length - 1 index, it is traversed as an array."
jQuery() has length == 0, and no value at index -1, so by definition it will not be considered array-like!
But strangely if the empty jquery is from an iframe, $.map correctly enumerates all properties: #8995.
Silly? Nooooo

That is the correct behavior. map iterates through elements, not the prototype. There may be some debate on the related tickets, but this one needs to stay the way it is.

Understood, #8995 presents a possible bug. Please do not open tickets to make points.

jQuery core does not have a need for this corner case to work as described, so this enhancement seems unnecessary.
Irony at side. Will not fill any further related ticket, I promise, but please reconsider this new crazy feature, even if it was voted by 1E3 persons.
