F-Viera ears bend when moved.

[AitchCee]

Describe the bug
Upon rotating the viera's ears via parented bones, the ears will bend out of position. This will only happen one time per enabling of posing mode, and so they can be adjusted back to their original position. This will not occur if you directly adjust the ear bones manually before rotating parent bones, meaning the issue can be somewhat circumvented by making slight changes to the ear bone rotations before rotating anything else. All ears display somewhat different behavior;

Ear type 1 (Pointed backwards with ear fluff): Selecting any parent bone will have the right ear shoot forwards, and upon bone rotation will have the left ear jump slightly back.

Ear type 2 (Straight up with ear fluff): Upon selecting any parent bone, The right ear will jump forward slightly, upon bone rotation the left ear will jump back further.

Ear type 3 (Floppy): No abnormal behavior.

Ear type 4 (Straight up with no fluff): No change upon selecting parent bones. Upon rotating, the right ear will jump back.

These were tested from a neutral standing pose, but loading certain custom poses can also seemingly trigger different behavior as well. For example, upon loading a custom pose I had made for my Ear 4 viera in patch 6.1 and rotating her neck, both the left and right ear jump backwards, instead of just the right.

To Reproduce
Steps to reproduce the behaviour:

1. Enter posing mode
2. Select any bone that is parent to the ears. Lumbar, Face, and Neck are the most common.
3. Rotate that bone along any axis using either the orb or the + and - buttons, all will reproduce this behavior.

Expected behaviour
Normally I would be able to rotate any parent bones without affecting the relative rotation of my ears.

Log file
I do not have a log file but I do have a video of this happening with a custom pose.

Hey Aitch i'm Qayar we talked about this in the Discord, i just saw #1158 which is a very similar issue, you can confirm is the same behaviour?

It is similar but not exact. In my testing with F-Viera ears, only one ear (the right one) actually moves when selecting a parent bone. Further movement of the ears will not occur until they are indirectly rotated via a parent bone. Also, they don't stand straight up but rather tend to point at an angle, though custom poses can greatly affect the ears overall behavior.
