This snippet:

```julia
using AbstractPlotting, Makie, Random

scene = Scene(resolution = (1200, 1500))
poly = Vec2f0.(1:10, rand(10))
labels = ["$i" for i in 1:10]
scatter!(scene, poly, color = :blue)
annotations!(scene, labels, poly, textsize = 0.01, color = :green)
display(scene)

```

produces:

Looking at documentation [https://makie.juliaplots.org/dev/abstractplotting\_api.html#AbstractPlotting.annotations!-Tuple](https://makie.juliaplots.org/dev/abstractplotting_api.html#AbstractPlotting.annotations!-Tuple) it seems that arguments to `annotations!` are OK. Can someone point me in the right direction?

Changing `poly` type from `Array{Vec{2,Float32},1}` to `Array{Point{2,Float64},1}`, i.e.:

```julia
poly = Point.(1:10, rand(10))

```

produces expected behavior.
