VRM1 LookAtTarget incorrect when character not in default orientation at Start

Environments (please complete the following information):

• UniVRM version: 0.131.0
• Unity version: Unity-2023.2.22f1
• OS: Linux

Describe the bug

VRM1 LookAtTarget incorrect when character not in default orientation at Start. If the character is not rotated to default global rotation (0, 0, 0), then LookAtTarget will be visually incorrect.
Example: Character starts with rotation (0, 180, 0) then when look at target is positioned above the character, the eyes will look down and if positioned below, the eyes will look up. This is the opposite of expected behavior (look up when target is above, look down when target is below).
This is not the case when the character starts with rotation (0, 0, 0) and then rotates later.
