Stairs refuse to render edges leading to 0 under y-logscale

[Moelf]

Encountered in:

• [Makie] stephist missing edges when some bins are empty in the middle of the histogram Moelf/FHist.jl#109

Pure Makie reproducer:

julia> using CairoMakie

julia> edges = [0:3; 3]; heights = [0, 2, 0, 10, 0];

julia> stairs(edges, heights)

julia> stairs(edges, heights; axis=(; yscale=log10)); ylims!(1, 100); current_figure()
