Tbird 128.3.1esr (64-bit), MacOS 14.6.1. In my setup there is no problem moving to/copying to (nested) subfolders. But when trying to move a collapsed thread indeed only the top email is moved. A very simple work-around is to expand the thread and select all emails (a few key strokes), then the move works as desired. This remains the single most important add-on for me, allowing efficient maintenance of a hierarchical database of emails. My life is better for it!!
