Unable to pass strokewidth vector into GLMakie for varying outline sizes

[ericchenanpt]

• [X] what version of Makie are you running? => [ee78f7c6] Makie v0.21.9, [e9467ef8] GLMakie v0.10.9
• [X] can you reproduce the bug with a fresh environment? => activate --temp; add GLMakie
• [X] What platform + GPU are you on? Windows, Intel(R) Iris(R) Xe Graphics

using GLMakie

fig = Figure()
Axis(fig[1,1])
kwargs = (; markersize = 30, strokecolor = :tomato)
scatter!(fig[1, 1], 1:3; kwargs..., strokewidth = 3)
Axis(fig[1,2])
scatter!(fig[1, 2], 1:3; kwargs..., strokewidth = [0,3,6])
fig

This error also shows up with LScene or Axis3, far as I can find.

Any insight would be helpful! Thank you.

This works fine in CairoMakie:

but not in the GL backends. On WGLMakie I get
