scatterlines cannot pass a number as one colorant for the whole scatterline

• are you running newest version (version from docs) ?
  CairoMakie v0.11.5
• can you reproduce the bug with a fresh environment ? (]activate --temp; add Makie)
• What platform + GPU are you on?
  AMD R5 2700 + RX 580

using CairoMakie
scatterlines(1:10,1:10,color=5,colormap=:jet,colorrange=(1,5))

The above codes cannot work and print this: ERROR: MethodError: Cannot convert an object of type Float32 to an object of type Union{ColorTypes.RGBA{Float32}, Vector{ColorTypes.RGBA{Float32}}, Vector{Float32}}

However, this works in lines and scatter

lines(1:10,1:10,color=5,colormap=:jet,colorrange=(1,5))
scatter(1:10,1:10,color=5,colormap=:jet,colorrange=(1,5))

A feasible solution is using vector as follows:

scatterlines(1:10,1:10,color=[5 for _ in 1:10], colormap=:jet, colorrange=(1,5))

but the color of scatter is differ from line. I have to set markercolor and markercolormap and markercolorrange, it's very inelegant.

In addition, the above codes which set one colorant to object from a colormap will results in a legend error.
Then I found another approach:

using Makie.ColorSchemes
mycolor = ColorSchemes.get(colorschemes[:jet], range(0, 1, 5))
scatterlines(1:10,1:10, color=mycolor[5])

Is it the only correct solution?
