Spurious minor ticks on y axis

[maxfreu]

Hi! I found a spurious y minor tick in my plot, a haunting ghost that should not be there!

• are you running newest version (version from docs) ?
• can you reproduce the bug with a fresh environment ? (]activate --temp; add Makie)

Problem:

Code:

using CairoMakie

mm2pt(x, dpi=72) = x * dpi / 25.4
let
    fig = Figure(size=mm2pt.((80,60)))
    ax = Axis(fig[1, 1], xlabel = "Δr [m]",
        ylabel = "Cumulative Density",
        xticks = 0:5:40,
        yticks = 0:0.2:1,
        xminorticksvisible = true,
        yminorticksvisible = true)
    Makie.lines!(ax, [0, 20.75, 20.75], [0.95, 0.95, 0], linestyle=:dash, color=:black)
    xlims!(ax, 0, 40)
    ylims!(ax, 0, 1)
    fig
    save("spurious_minortick.png", fig, px_per_unit = 2, pt_per_unit=1)
end
