SUMMARY Each time main KMail/Kontact window is activated or deactivated its mail list is refreshed and currently selected mail is lost. STEPS TO REPRODUCE 1. Open some mail directory (and keep in mind which mail was selected). 2. Select one or other mail (not the same which was selected on directory switch). 3. Switch to another app, for example Alt+F2 (Alt+Space) to run KRunner, that doesn't matter. OBSERVED RESULT I. Current directory content list is refreshed. II. Selected mail switches back to that from step 1. (NB Selected mail is kept on switching mail directory) EXPECTED RESULT I. I can't see a reason to refresh list on activation/deactivation, though maybe I'm wrong and there is some reason. But flashing to empty and showing list again doesn't look good. II. At least selected mail should be kept on deactivation/activation. SOFTWARE/OS VERSIONS Linux/KDE Plasma: openSUSE Tumbleweed (snapshot 20190305).
