System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 550 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 376.54

Blender Version
Broken: version: 2.90 (sub 2), branch: master, commit date: 2020-05-20 08:43, hash: 578b0c00ca
Worked: (newest version of Blender that worked as expected)

Short description of error
clearing transformations in pose mode does not affect the mirrored bones even when the X-axis mirror is activated.

Exact steps for others to reproduce the error

Open the .blend file move the last bone "antenna_3.L"
Move it downward so that other bones move along ( auto IK and X-axis mirror are enabled )
Now select all the bones on your right side ( .L bones) clear the rotation with Alt+R

Notice that only bones from your right side will clear their transformations but bones on your left side ( .R bones ) are still on the same pose.clear-x-mirror.blend

In my case, clear the location (Alt + G), is not doing anything.
Am I doing something wrong?

Did you moved the bone first?
I see, i was not clear, it is Alt+R that should clear since bones are auto-IK, Alt+G doesn't anything here as well. This is just my old habit when i clear i clear everything.
So after you moved the bone (in the given .blend file), select all .L bones then Alt+R.
Sorry for that.

The mirror transformation into pose mode is a specific feature of the transform operators.
So operators like POSE_OT_rot_clear will not affect mirrored bones.
We could think of something like D6736 and use a common function to update the mirror on different operators.

I am not sure if we can consider this an bug/error, but I will confirm it as a bug for now.

@mano-wii: I would think this is more of a TODO [since it is just not implemented -- and not a bug in current code.]
(feel free to change back to your liking though)

I tried to reproduce this bug (master @ fab39440e9) but I can't. Could it have been fixed as part of other work on the transform system? @mano-wii do you still think D6736 is necessary?

Apparently this report is a duplicate of #83657 (Pose Mode: Clearing transform doesn't respect Mirror X) which was resolved by f7a5695676
D6736 proposes to implement the update of mirrored bones when changing properties (in the UI).
Perhaps the utility proposed in that patch can be used to be called in some depsgraph node. (an idea to solve all possible cases)
