TYPO3 Core

Unfortunately it pastes text with and without structure.
As you can see in the screenshot.

Google Chrome Version 43.0.2357.124 m

Backend user configuration

setup.override {
    rteCleanPasteBehaviour = pasteStructure
}

RTE configuration

    hideButtons *
    showButtons (
        bold, italic, subscript, superscript, chMode, indent, outdent, pastetoggle,
        orderedlist, unorderedlist, formatblock,
        insertcharacter, link, findreplace, undo, redo, about, blockstyle
    )
buttons.pastetoggle.setActiveOnRteOpen = 1

Can you please take a look at this Problem? Thanks a lot in advance.
