Description mao 2022-02-21 15:22:54 UTC 
Steps to reproduce:
- login fresh user account
- start KMail, cancel account assistant
- start compose new message, not fill any fields
- save message as draft, go draft folder, view message
- now output lots of "org.kde.pim.akonadiserver: ItemRetrievalJob for request XXX finished" warnings and CPU usage stays at 100% -> computer unusable :-(

Can also be observed with regular messages received in inbox if message body empty, e.g. if sender just says "Hi!" in subject.

Hope for fix! Thanks!

Can confirm on Operating System

openSUSE Tumbleweed 20220218
KDE Plasma Version: 5.24.1
KDE Frameworks Version: 5.90.0
Qt Version: 5.15.2
Kernel Version: 5.16.8-1-default (64-bit)
Graphics Platform: Wayland

though my CPU runs at 3% instead of ~0.5%, but it may be somewhat faster.
