I would like to add a default theme when plotting a custom type. I tried the following, but the `default_theme` method is never called:

```julia
using Makie
using AbstractPlotting

struct MyArrowData end

function AbstractPlotting.convert_arguments(P::Type{<:AbstractPlot}, o::MyArrowData)
    pos = [randn(Point3f0) for _ in 1:100]
    vel = [randn(Vec3f0) for _ in 1:100]
    AbstractPlotting.convert_arguments(P, pos, vel)
end

function AbstractPlotting.default_theme(scene, ::Type{<:MyArrowData})
    Theme(
        linewidth=0.01,
        linecolor=:red,
    )
end

arrows(MyArrowData())

```
