Triangle fill color applied everywhere after zooming in (`xlims`/`ylims`) and saving (`savefig`)

Possibly related: the SVG export also does not work correctly (the line is drawn in the wrong place):

julia> savefig("1.svg")

With a different view area, it can be seen that the PNG export is off in one direction, but the SVG export is off in the other direction. The triangle should go through (0, 0), which I marked in the plots below:

julia> using Plots
julia> x, y = ([1000.1, -1000.1, 1000.1, 1000.1], [1000.1, 1000.1, -1000.1, 1000.1]);  # same as before
julia> plot(x, y; seriestype=:shape, xlims=(-0.017, 0), ylims=(-0.008, 0.004))
julia> scatter!([0], [0])  # mark (0, 0)
julia> savefig("1.png")
julia> savefig("1.svg")
