- This precents us from logging two ICEvents for a megamorphic miss that adds
  a new property
- We don't have to reset the profiler ticks anymore for this miss

The particular case for missing to add a new property happens ~1700 times in
the Speedometer Angular benchmark where we get an already internalized key
as property name.
