Quick Drag and Drop Tiles example broken in Qt 6

Example in Qt-6.2.2\quick\draganddrop\tiles seems to be broken. It is working in 5.15.2.

There are two gifs in attachments

6.2.2.gif shows current apparently wrong behavior.

6.2.2 fixed.gif shows correct behavior which is the same as in 5.15.2. To achieve that, I had to make changes to tile's states property in DragTile.qml:

states: [
  State {
    when: mouseArea.drag.active
    ParentChange { target: tile; parent: root }
    AnchorChanges { target: tile; anchors.verticalCenter: undefined; anchors.horizontalCenter: undefined }
  }
  ,State {
    when: !mouseArea.drag.active
    ParentChange { target: tile; parent: mouseArea }
    AnchorChanges { target: tile; anchors.verticalCenter: mouseArea.verticalCenter; anchors.horizontalCenter: mouseArea.horizontalCenter }
  }
] 

Adding a new state which resets parent and anchors to their original values seems reasonable and makes me wonder how it worked before without that change. The same fix worked for me in our production code when we migrated from Qt 5 to Qt 6.

Is this a Qt bug? If this is not a Qt bug, but an intended behavior change, I haven't found any warnings and migration guidance.

Please, kindly provide a better solution, if any.
