TYPO3 Core

I have the following configuration:

lib.parseFunc_RTE.externalBlocks.table.stdWrap.HTMLparser.tags.table.fixAttrib.class.list = contenttable, sofa1, sofa2, sofa3, sofa4

When a table has a class not in the list above, the result is not 'contenttable' as expected, but an empty class.

In class.t3lib_parsehtml.php line 827 the current code is:

if (count($newClasses)) {
$tagAttrib⁰[$attr] = implode(' ', $newClasses);
} else {
$tagAttrib⁰[$attr] = '';
}

I think that has to be:

if (count($newClasses)) {
$tagAttrib⁰[$attr] = implode(' ', $newClasses);
} else {
$tagAttrib⁰[$attr]=$params['list']⁰;
}
