System Information
Operating system: Windows-10-10.0.22621-SP0 64 Bits
Graphics card: AMD Radeon(TM) Graphics ATI Technologies Inc. 4.5.0 Core Profile Context 23.4.3.230420

Blender Version
Broken: version: 3.3.7, branch: master, commit date: 2023-05-22 12:03, hash: 659c307f2502
Worked: (newest version of Blender that worked as expected)

Short description of error

When Selecting a Bone to Rotate on Pose Mode, the first instance of Bone Rotation is not being 'free' (Global) by default, but 'locked' on some other (Local?); even though I've got Transform Orientations on Global

Exact steps for others to reproduce the error

Started a new project;
Added a Bone (Armature Object);
Went on Pose Mode;
Press [ R ] to Rotate randomly (Transform Orientation is already set to Global by default);
Realize it's not Rotating on Global, unless Pressed [ R ] a second time (so to Toggle between Local/Global/etc.), but shouldn't be the inverse?

I do not know any configuration in Blender that would change this order of functionalities, as it never happened to me before (although I've recently changed my OS); so I suspect it's a bug from later Blender LTS 3.3.7; I used to use LTS 3.3.1.

Hi, I'm not sure I could replicate the issue:

The file is in Edit mode, the bone in edit mode will rotate to a minimal twist state \if not constrained, and when rotating it freely the rotation along the local Y is gonna change.
In Pose mode, when rotated freely, the bone is not twisting. (Tested on 3.3.7)
Pressing R again in pose mode or edit mode will both toggle the rotation to an "Orbit" mode rather than going to global/local, so not sure what your intention is. Do you want to get the R R rotation on bones the first time you press R?
