[Bug] grass.jupyter.TimeSeriesMap incorrect layer rendering

[petrasovaa]

Describe the bug

TimeSeriesMap is not rendering the layers correctly.

To reproduce

In doc/examples/notebooks/temporal.ipynb this example results in incorrect rendering:

precip_map = gj.TimeSeriesMap(use_region=True)
precip_map.add_raster_series("precip_sum_2010")
precip_map.d_legend(color="black", at=(10, 40, 2, 6))  # Add legend
precip_map.d_vect(map="boundary_county", fill_color="none")
precip_map.d_barscale()
precip_map.show()

Expected behavior

The boundary layer and scalebar should be visible.

System description

This is in main branch only.

Additional context

Probably caused by some changes during last year GSoC. SeriesMap which has the same base class as TimeSeriesMap is working fine.
