JMeter Run Duration Exceeds

### Expected behavior

We have configured our script using include controller, and configured the test duration for 1 hour, expected should be completed within 1hour.

### Actual behavior

If include controller is been added in the script the execution is prolonged for more than an hour it actually runs 7 to 8 hours eventhough the run setting is configured for 1hour.

we did another run without include controller, the run went fine completing the targeted samples in 1hr.

Is it possible that due to include controller the run duration will get extended....

### Steps to reproduce the problem

1. Create a script with any site.
2. Add simple controller and save as test fragment.
3. Now add include controller under thread group.
4. configure the test fragment in the include controller.

### JMeter Version

5.6.3

### Java Version

open jdk version 8

### OS Version

Microsoft windows

Reproduce the report on JMeter 5.6.3 with OpenJDK 8 on Windows, comparing a one-hour test with and without an Include Controller and a test fragment. Start by checking the Include Controller and test-duration behavior, then determine whether the extended run is expected or indicates a defect; done means the behavior is explained or a narrowly scoped fix is identified.
