Does Gazebo 7 Ignore the SDF Pose Element for Fixed Joints?

I believe the answer is yes but wanted to make sure. My SDF joint definition is as follows:

<joint name='myJoint' type='fixed'>
  <pose>0 0 0 0 0 0</pose>

I can change the <pose> element to be any arbitrary value and Gazebo 7 would show the robot as if the joint still had zero pose. Is this expected?

What behaviour were you expecting to see? I think the joint pose doesn't matter for a fixed joint, no matter where it is, the links will maintain their initial relative pose.

@chapulina what you are saying is true...! I also checked this behavior. Changing the <pose> element of the joints for fixed joints does not change the pose.

I get the same behaviour with Gazebo 11 and ROS2 foxy
