openSUSE adventures - Leaped onto Tumbleweed, tumbled for a while and rolled back on to Leap due to a Dolphin bug

KDE Plasma's official File Manager, Dolphin, has a bug which forced me off of openSUSE Leap 15.2. I installed openSUSE Tumbleweed in the hope that the newer versions of KDE Plasma might have gotten rid of the bug. I was shocked when I saw the dangerous bug eerily smile at me in openSUSE Tumbleweed.
