 /var/folders/4g/sjfdskjgdsklfi098ds09jsejre/T/mozDraggedFiles/<subject_of_email>.eml Already exists do you want to replace it? Y/N

Since a few weeks ago every time I try to drag an email from the inbox to a folder (I'm not ever trying to drag it out of Thunderbird), if I falter with the mouse or try to drag it a second time I get dialog box asking if I want to replace a file that already exists in the "mozDraggedFiles" folder. e.g.: '''CONFIRM''' ''/var/folders/4g/sjfdskjgdsklfi098ds09jsejre/T/'''mozDraggedFiles'''/<subject_of_email>.eml Already exists do you want to replace it? Y/N'' Clearly a temp folder for stored copies of emails before they get moved/copied somewhere. There's a similar bug reported here: https://bugzilla.mozilla.org/show_bug.cgi?id=1983616 Which links to another couple of bugs, but all are talking about dragging files to desktop or other location but not about dragging them within the program. Presumably once a dragged email reaches it's destination the copy in the mozDraggedFiels folder ought to be cleared right? I wonder why that has changed recently, I'm pretty sure I haven't had this issue before. Also to make matters worse when the dialog box comes up, it is only displayed locally to the machine to screens connected directly to it and if I am remoting in with share screen or something like jump desktop the machine essentially hangs/disconnects until the dialog box is closed! Anyone else getting this ? I'm on OSX 15.1 and Thunderbird143.0.1 (aarch64) R.
