The Queryparameter `processInstanceIdIn` doesn't work on the resource `historic/variable-instance`. The request on the resource with the given parameter returns all historic variable instances, so it seems the filter will not be applied. The documentation doesn't mentioned the query parameter but it exist a property and test cases for this.

See the following code positions:

• HistoricVariableInstance.xml
• HistoricVariableInstanceRestServiceQueryTest.java
• HistoricVariableInstanceQueryDto.java

AT:

• request with `processInstanceIdIn` on `historic/variable-instance` returns only the historic variable instances for the given process instance id's
