Prevent tiles from turning grey with Zoom In

Is there a way with Bokeh to zoom in further and just get extra pixelated tiles? Even though they are pixelated it is more useful than having them turn grey.

Side reference, there appears to be a way with Leaflet:

@Eric_Johnson you will need to provide more details, including version info and a complete Minimal Reproducible Example. If I try zooming in the example renderer in the docs I never see any grey tiles, and the tiles do start to pixellate.
