I did and attached the screenshots but it's blocked by the list until aproved.
there are 4 threads using resources but their TID is not listed in the
processlist nor in the performance_schema.threads table.

also I did the same in another server (I have some identical servers with this
new pristine setup for a greenfield scenario) and I can reproduce it in the
second server. Very weird.
