50 is fairly short, 300 as used in systemsettings is much nicer
and also makes the two uis behave the same
BUG: 393722
FIXED-IN: 5.18.0
why ever do we have a code copy of the same tooltip manager inaids in making kinfocenter and systemsettings behave with the
both uis...same delay. plus not hardcoding things is always cool
