SUMMARY
Split window can't be activated / focused by a mouse click when a specific location is set for the startup of Dolphin.

STEPS TO REPRODUCE
1. Start Dolphin
2. Open "Configure Dolphin..." and enable "New Windows: Begin in split view mode" and
3. Set "Show on startup:" to a specific location (e. g. /home/username/)
3. Close Dolphin
4. Start Dolphin

OBSERVED RESULT
Focusing a specific split window by clicking with the mouse won't actually focus that half.
Also, when browsing through folders via the Places panel (e. g. Desktop; Documents; Downloads; Pictures, etc.), one folder first opens on the right split window, then on the left, then on the right again, and so on.
Focusing by mouse click only works after entering a folder through one of the split windows or by using Tab as a shortcut to switch between windows.
If "Show on startup:" is set to "Folders, tabs, and windows from last time", activating a split window works as expected.

EXPECTED RESULT
Activating a split window by clicking with the mouse should always behave the same (= actually work), independent of the "Show on startup:" setting.
