vNext: Incorrect type returned for the floor scale in the boundary visualization profile

[david-c-kline]

Does this affect the legacy HoloToolkit (master) or the Mixed Reality Toolkit (mrtk_release)?
Mixed Reality Toolkit

Describe the bug

[SerializeField]
[Tooltip("The dimensions of the floor, in meters.")]
private Vector2 floorScale = new Vector2(10f, 10f);

/// <summary>
/// The size at which to display the rectangular floor plane <see cref="GameObject"/>.
/// </summary>
public Vector3 FloorScale => floorScale;

Expected behavior
The FloorScale type to match the floorScale type.

Actual behavior
Type mismatch
