Compacting folders offers more space than the size of disk despite not keeping any local copies. How/why?

I have almost the same configuration of Thunderbird on two different Linux computers. In about past two days both went crazy, offering me to free 500 GB on my laptop (actual disk size is 256 GB, Linux partition even smaller) and 616 GB on my desktop (where the disk size is 512 GB and partition again smaller).

What confuses me even more is fact that I have on all my accounts setting that prevents Thunderbird from saving any messages to local disk (Account Settings > Synchronization & Storage > uncheck "Keep messages for this account on this computer"). All my accounts are IMAP based so I literally should not have any messages on my disk at all, only last couple of days in cache.

I almost feel like reporting a bug but I want to ask here first. Any explanation?

There was a similar thread this week where a moderator said it is a known issue with no fix so far.

Thank you for your reply. I tried to search but didn't find anything related to this. A link would be helpful but not necessary, I will just have to wait for fix.

Best regards.
