MapLayersWidget - sections of background map are not visible around the imodel

[Jake-Screen]

We are utilizing the MapLayersWidget to provide a background map in our studio application. When adding this to application we use a classId of "UnifiedSelectionViewportControl2D".

Upon loading an iModel from iModel hub, the map appears blank around the area where our model is centered. Upon zooming out, some parts of the map appear, with clipping appearing in different sections of the map. When zoomed far enough out, we can see a circle of area that is not covered in map.

Expected behavior
For the map to be visible in the area of our iModel.
