I'm glad for you.

Today I brought up a new Kubuntu 19.04 VM (kmail 5.10, mysql  Ver 14.14 
Distrib 5.7.26); configured Kmail & accounts from scratch.

The issue is still present...

This issue refers to all messages which were already fetched by Kmail and then 
read on another client. Newly fetched messages by Kmail but already read on 
Thunderbird are marked correctly.
