[BUG] Plots segfaults in GR

[Keno]

The below test case crashes in GR. Sometimes in longjmp, sometimes in process_glyphs.

Details

Note: This may not be a correct use of the API, but in any case, ideally it shouldn't crash.

using Pkg
Pkg.add(url="https://github.com/CedarEDA/MDMReader.jl.git")
Pkg.add(url="https://github.com/CedarEDA/skywater-pdk-sky130-raw-data.git")
Pkg.add("PlutoUI")
Pkg.add("Plots")
Pkg.add("StatsPlots")

using MDMReader, var"skywater-pdk-sky130-raw-data", PlutoUI, Plots, StatsPlots
cells_dir = joinpath(dirname(pathof(var"skywater-pdk-sky130-raw-data")), "../sky130_fd_pr/cells")
device = "esd_nfet_01v8"
file = "sky130_fd_pr__esd_nfet_01v8_w20p35u_l0p165u_m1(4044_4_5_IDVD).mdm"
mdm = MDMReader.parse_mdmfile(joinpath(cells_dir, device, file));
@df mdm.data plot(:VD, :ID, label=[:VG, :VS, :VB])

Should this be filed in GR.jl?

julia> pl = @df mdm.data plot(:VD, :ID, label=[:VG, :VS, :VB]);

julia> pl[1][1][:label]
3-element Vector{String}:

Is probably not what you wanted. I suspect this is another case of https://github.com/JuliaPlots/Plots.jl/issues/4198

Should be fixed with GR 0.66.2
