defaults to grid(False) for dotplots using seaborn objects so.Dot

[Xparx]

Trying to plot with the seaborn objects.
Using so.Dot()
the following line when commented out reintroduce the grid options.

I don’t understand.

Sorry for being unclear. I'm trying to use the new seaborn interface for plotting.

I'm trying to make a Dot plot with grid lines

sns.__version__
'0.12.1'

the problem is i can't get the grid lines to show up even using

if I just use the following code snippet

fig = plt.figure(figsize=figsize, constrained_layout=True, dpi=dpi)
ax = fig.add_subplot(111)
ax.grid(linestyle='--', lw=0.2)
ax.set_axisbelow(True)

p = (
    so.Plot(
        tmp,
        y="y",
        x="x",
        color="p_value", 
        pointsize="Ratio",
    ).add(so.Dot(edgecolor='k')).on(ax).label(x='bla1', y='bla2')
    .scale(color="flare", pointsize=(1, 20))
    .theme({"axes.facecolor": "w", "axes.grid": True, 'axes.axisbelow': True})
)
p

I get an output (using jupyter-notebook)

I don't get any grid lines, if i comment out the line in plot.py
# axis_obj.grid(False, which="both")
and use the same code I get

I have tried a few different combinations of grid commands, but without commenting out the the line I get no grid lines.
However if I use

fig = plt.figure(figsize=figsize, constrained_layout=True, dpi=dpi)
ax = fig.add_subplot(111)
ax.grid(linestyle='--', lw=0.2)

p = (
    so.Plot().on(ax)
    .theme({"axes.facecolor": "w", "axes.grid": True, 'axes.axisbelow': True})
)
p

I get grid lines even without commenting out the line. Adding data removes the grid lines.
(please note I tried to make the code more readable so figure legend is missmatching).
I do need to use an external ax.grid command either way.

I don't see how the link helps me figure out how to get grid lines.
Where should I look for that. Or are you suggesting that they are not available at all?
