ObjectSpace::AllocationTracer.clear doesn't clear allocated_count_table result

[amatsuda]

require 'allocation_tracer'

ObjectSpace::AllocationTracer.trace { a = a = 'hello' }

p allocated_count_table: ObjectSpace::AllocationTracer.allocated_count_table.select {|_, v| v > 0}

ObjectSpace::AllocationTracer.clear

p allocated_count_table_after_clear: ObjectSpace::AllocationTracer.allocated_count_table.select {|_, v| v > 0}

p trace: ObjectSpace::AllocationTracer.trace { }

#=>
{:allocated_count_table=>{:T_STRING=>1}}
{:allocated_count_table_after_clear=>{:T_STRING=>1}}
{:trace=>{}}

Is ObjectSpace::AllocationTracer.allocated_count_table intentionally uncleared?
