HistoricProcessInstanceQuery also query task variable

Describe the bug when use HistoricProcessInstanceQuery with variable value, it also query query task variable with the same name

Expected behavior HistoricProcessInstanceQuery only query process variable

Code

HistoricProcessInstanceQuery query = historyService
          .createHistoricProcessInstanceQuery()
          .processInstanceId("abc")
.includeProcessVariables();
query.variableValueEquals("process_variable", "process_variable_value");
query.count();

this query produce a sql :

select
    count(distinct RES.ID_)
from
    ACT_HI_PROCINST RES
    left outer join ACT_RE_PROCDEF DEF on RES.PROC_DEF_ID_ = DEF.ID_
    inner join ACT_HI_VARINST A0 on RES.PROC_INST_ID_ = A0.PROC_INST_ID_
WHERE
    RES.PROC_INST_ID_ = ?
    and A0.NAME_ = ?
    and A0.VAR_TYPE_ = ?
    and (A0.TEXT_ = ?)

the right sql should be

select
    count(distinct RES.ID_)
from
    ACT_HI_PROCINST RES
    left outer join ACT_RE_PROCDEF DEF on RES.PROC_DEF_ID_ = DEF.ID_
    inner join ACT_HI_VARINST A0 on RES.PROC_INST_ID_ = A0.PROC_INST_ID_
WHERE
    RES.PROC_INST_ID_ = ?
    and A0.NAME_ = ?
    and A0.VAR_TYPE_ = ?
    and (A0.TEXT_ = ?)
    and A0.TASK_ID_ IS NULL

Additional context flowable: 6.6.0 , 6.7.0
database: mysql
