TYPO3 Core

When moving elements around in workspaces, there are two additional records used to mark the former position and the target position.
The t3ver_state MOVE_PLACEHOLDER (3) and the t3ver_state MOVE_POINTER (4) are then used to create labels according to that position.

case new VersionState(VersionState::MOVE_PLACEHOLDER):
    $parts[] = 'NEW LOCATION (PLH) WSID#' . $row['t3ver_wsid'];
    break;
case new VersionState(VersionState::MOVE_POINTER):
    $parts[] = 'OLD LOCATION (PNT) WSID#' . $row['t3ver_wsid'];
    break;

But actually the PLACEHOLDER marks the OLD LOCATION, while the POINTER marks the NEW LOCATION.

Just got confused by that while digging deeper into workspace problems of Gridelements.
