SUMMARY
***
Running openSUSE Tumbleweed, latest updates, KDE Plasma desktop. Using both Dolphin and Krusader as file managers, both in split-window mode (old Norton Commander habit...). My issue is which of the two Dolphin windows has the focus when Dolphin starts; there is no issue with Krusader.

I want the focus to be on the l.h.s. window [column] when I start Dolphin. Thus, in Dolphin Preferences, I set "Start" -> "Show at start" -> "Folders, sub-windows, window status as of last start" (translated from German).

However, annoyingly, Dolphin always comes up with the focus on the r.h.s. window [column]. It doesn't help to exit Dolphin after setting focus to the l.h.s., and there is no setting in Preferences I can chose to help either.
***

STEPS TO REPRODUCE
1. Set Dolphin Preferences to display the menu bar and to be in split-window mode at its start, and try several settings regarding folder / window status restore at start
2. Set focus onto l.h.s. window [column], then exit from Dolphin
3. Start Dolphin again

OBSERVED RESULT
Dolphin always comes up with focus on the r.h.s. window [column]

EXPECTED RESULT
Dolphin should come up with focus on the l.h.s. window [column], when the l.h.s. window had the focus at exit from Dolphin

Addendum: Tested it also on kubuntu 22.04 (latest),
with KDE Plasma 5.24.6, KDE Frameworks 5.92.0, Qt 5.15.3.

Observation: Identical annyoing behavior of Dolphin!

CONFIRMING this bug.

I've been running KDE Plasma on MX Linux for a few years now. Every edition I used so far has had this issue.

I also have it set to "Show on startup:  Folders, tabs, and window state from last time" , so when I close Dolphin with focus on the left pane I would always expect it to start with focus on the same side. I happen to agree that it is quite annoying.
