Subject: Improve arrow key navigation in Details View with expanded folders
X-Git-Url: https://cloud.milkyroute.net/gitweb/dolphin.git/commitdiff_plain/397f8783d98dea4f8a34b15bb0a2db82dc8b848e

Improve arrow key navigation in Details View with expanded folders

If the current folder is collapsed, pressing the left arrow key now
moves the focus to the parent folder.

CCBUG: 300582
(cherry picked from commit 93daadae28f7e3b5cffd7b713a2a287e4fa62ccd)
