JQuery creates "placeholder" attribute on every input element

Somehow JQuery silently creates an empty "placeholder" attribute on every input element. Try it out on the JQuery homepage with


or native


Both will give "" as a result, while really they should be undefined (compare with a page with an input and no JQuery).

This needs to be fixed because in the current situation, it is impossible to detect whether an *empty* placeholder attribute is present or *no* placeholder attribute is present. This can hinder development of plugins that show custom placeholders.

 jQuery does return undefined. You can't use the frontpage as a test, since it's using an older jQ version.

Please follow the  bug reporting guidlines and use  jsFiddle when providing test cases and demonstrations instead of pasting the code in the ticket.
