TYPO3 Core

in t3lib_befunc::getTCEFORM_TSconfig(), non array values are not added to the returned conf array.

Exemple: this TSConfig, set in a page, is not considered nor returned by the method:
TCEFORM.tt_content.hello = World

Whereas this one is:
TCEFORM.tt_content.hello.dear = World

This is due to the fact that line 3223 if (is_array($val)) { processes only array values to merge them in the resulting conf array, whiteout counterpart for non-array values (no else).

To fix this, add these instructions at line 3230:

} else {
    $res[$key] = $val;
}

This impacts a lot of things (for me, the inability to set TCEFORM.tt_content._STORAGE_PID from Page TSConfig), and I suspect that many bugs in the BT are related to this (noticeably #30864)
