This feature depends on "Display informational tooltips on mouse hover" option available in General Behavior KCM, which was unchecked on my system. At first glance this may seem confusing because tooltips of Dolphin work even when mentioned option is unchecked. But now I understand that the option available in General Behavior KCM only takes effect on Plasma, not all KDE softwares. Tooltips show up as expected when "Display informational tooltips on mouse hover" option is checked.
