Description

When the bullet-featherstone physics engine is used with gz harmonic, the controllers are not getting into active state and are getting timed out. sometimes, even if they are transitioned into active state, I am unable to control the joints. When the plugin is changed to default or dartsim, the controllers are being loaded and executing as expected (however, they dont support mimic joints as we are aware)

Steps to reproduce

1. ros2 launch gz_ros2_control_demos gripper_mimic_joint_example_position.launch.py
2. ros2 run gz_ros2_control_demos example_gripper
3. you can observe that the gripper joints are not moving.

This is happening not just with the demo, but also with the custom packages that I am working with.
