*Repro:*
# Open the project from the attached .zip.
# Open Assets -> Scenes -> 01_MainMenu and view the Game Scene.
# Set Game Scene resolution to Free Aspect.
# Open MainMenu.uxml (Assets -> UI Toolkit -> UI Assets -> UXML) in the UI builder.
# Ensure ‘Match Game View’ is selected on the Canvas.
# Adjust the Game view size to see how it affects the canvas in the UI Builder viewport.

*Expected Outcome:* The Viewport in the UI Builder matches what you see in the Game View

*Actual Outcome:* The UI in the viewport looks very different from the Game View. See attached image.

Reproducible in 2023.1.0b3, 2021.3.18f1 - marking as not a regression.

Have not extensively regression tested the issue - please contact the assigned ticket reporter if you need further testing or information.

*Note:*
* Have only seen this happen when Panel Settings has Scale Mode set to ‘Scale with Screen Size’ and the Reference Resolution is set.
