TYPO3 Core

TYPO3\CMS\Filelist\FileList::makeRef() contains the following code:

        return '
            <button ' . GeneralUtility::implodeAttributes($attributes, true) . '">

There is an unnecessary quote. It produces html as follows:

<button type="button" class="btn btn-link p-0" data-filelist-show-item-type="_FILE" 
 data-filelist-show-item-identifier="1:/user_upload/easyweb/fotogalerie_hund3.jpg" 
 title="Show references (31)"">
