Steps:

1) Open the attached project.

2) Press Play

3) Open Frame Debugger

3) Enable it

5) Use slider or buttons and notice how the game view/selection does not change

6) Manually click on the left-side tree view items and notice how the selection does change.

Note: When using the left/right buttons, sometimes the selection does change but not always.

While this can be worked around by using the left tree view, quickly searching for a step in the rendering process is a lot more inconvenient. This was working as intended in Unity 2021 LTS (latest) which is why it was immediately obvious to be broken when updating.
