cannot create subplots of pie

**Describe the bug**
I have such code
```julia
using StatsBase, PlotlyJS, DataFrames
let nums = rand(1:10, 100)
cm = countmap(nums)
xs = collect(keys(cm))
ys = collect(values(cm))

df = DataFrame(xs = xs, ys = ys)

p = PlotlyJS.pie(df, values = :ys, textposition = "inside")

sp = make_subplots(rows = 1, cols = 2)
add_trace!(sp, p, row = 1, col = 1)
add_trace!(sp, p, row = 1, col = 2)
sp
end
```

what I expect is that there are two pie plots in the figure,
however there is only one pie plot
