Dolphin split view navigation jumps between panels

After my computer sleeps, or sometimes just after I haven’t used it for a while, when I go to a split view dolphin tab and try to navigate using the toolbar (up a level, back, etc.) the navigation will be applied alternately to each pane of the split. The only way to clear the behavior that I’ve found is to enter a directory on one of the panes, and then it stops…until it starts again the next time.

I’ve done some fairly extensive searching on these forums, Google, etc. and cannot find anyone else who mentions this behavior. Is it just my setup, somehow? Thoughts on how to troubleshoot/fix this?
