Barplot colors not working with PGFPlotsX backend

[blwh]

The argument color does not color the individual bars in a barplot when using the PGFPlotsX backend.

julia> using Plots; pgfplotsx();

julia> plot(1:3, 1:3, color=cgrad(:Set2)[1:3])

produces

However, switching to the default backend works.

julia> using Plots;

julia> plot(1:3, 1:3, color=cgrad(:Set2)[1:3])

produces

This was tested on Julia 1.9.4, Plots.jl 1.40.3 and StatsPlots.jl 0.15.7
