[BUG]MRTK3 RayInteractor hover works, but click doesn't select (Editor only, XR Device Simulator)

[gksdyd19]

Describe the bug
I'm using Unity 2022.3.21f1, MRTK 4.0.0-pre.1, and the new Input System. While testing in the editor using the XR Device Simulator, I can see hover interaction working correctly with RayInteractor, but clicking (via mouse left-button) doesn't trigger selection.

This only happens in the editor — the same scene works fine when built or when using a real HMD.

✅ Gaze-based interaction (hover + select) works perfectly even in the editor.

To Reproduce
Steps to reproduce the behavior:

1. Use RayInteractor with XR Device Simulator
2. Hover over UI element (hover works)
3. Press mouse left-click
4. Selection does not occur; ray direction changes unexpectedly

Expected behavior
Clicking while hovering should select the interactable object.

Platform info

• Unity version: 2022.3.21f1
• MRTK version: 4.0.0-pre.1
• Device: Editor with XR Device Simulator

Additional context

• attachTransform.rotation changes at click time
• Select action bound to <Mouse>/leftButton and pinch is triggered
• hoverInteractable and validTargets are set correctly
• Works fine in build and on HMD
