TYPO3 Core

The bug occurs when you want to link a content element in the RTE with the "Insert Link" action int TYPO3 7.6.4. All elements which have titles/content which is too long used to be converted into a tooltip. Now the element is rendered as clear text.

The element is transformed into a tooltip at the following file location:

sysext/backend/Classes/Utility/BackendUtility.php:2256

if ($titleOrig != $title) {
> $title = '<span title="' . $titleOrig . '">' . $title . '</span>';
}

Here its gets passed to htmlspecialchars():

sysext/recordlist/Classes/LinkHandler/PageLinkHandler.php:205

            $out .= '
                <li' . $selected . '>
                    <span class="list-tree-group">
                        <span class="list-tree-icon">
                            ' . $icon . '
                        </span>
                        <span class="list-tree-title">
                            <a href="#" class="t3js-pageLink" data-id="' . (int)$expPageId . '" data-anchor="#' . (int)$row['uid'] . '">
                            class="t3js-pageLink"    ' . htmlspecialchars(BackendUtility::getRecordTitle('tt_content', $row, true, null, true)) . '
                            </a>
                        </span>
                    </span>
                </li>
                ';
