With multiple split panel, Terminal is not responding to scroll using Surface Dial

[compulim]

Windows Terminal version

1.12.10733.0

Windows build number

22581.200

Other Software

WSL2: 0.56.2.0

Steps to reproduce

1. Use Windows Terminal to open Command Prompt (also tried WSL)
2. Split pane, so there should be 2 instances of Command Prompt opened side-by-side
3. On both panes, run dir for a couple of times until the scroll buffer is filled
4. Press-and-hold Surface Dial, set to scroll mode
5. Rotate on the Surface Dial

Expected Behavior

Rotating Surface Dial should scroll the active pane up/down.

Additionally, it should scroll on the pane where the mouse is hovering on, not focused (to follow mouse wheel behavior).

Actual Behavior

Rotating the Surface Dial will not scroll the pane.

If all but one of the split panes are closed, rotating Surface Dial will scroll the sole pane.

Hmm. That's entirely possible. Shame I don't have a Surface Dial around here to test with. @DHowett what are the odds we can requisition one to investigate?
