The fix is to set local-space Limit Rotation constraints to use the legacy behavior from pre-4.2. The legacy behavior isn't meaningful/ useful for other spaces, so we leave those constraints alone. This is one part of a two-part fix for blender/blender#123105. The other part is blender/blender#123361, which adds the Legacy Behavior option to the Limit Rotation constraint.
