I have a package that won’t successfully precompile because one of the plot methods in PlotlyBase that is extended to DataFrames isn’t recognized during precompilation. The package has the following Project.toml

```toml
name = "PlotlyDFTest"
uuid = "cb693c1a-2323-4e7d-a59f-d847e178de62"
authors = *********
version = "0.1.0"

[deps]
DataFrames = "a93c6f00-e57d-5684-b7b6-d8193f3e46c0"
PlotlyJS = "f0f68f2c-4968-5e81-91da-67840de0976a"
PrecompileTools = "aea7be01-6a6a-4083-8856-8a6e6704d82a"
Reexport = "189a3867-3050-52da-a836-e630ba90ab69"

```

and the module source file is:

```julia
module PlotlyDFTest

using PrecompileTools, Reexport

@reexport using DataFrames, PlotlyJS

@setup_workload begin
        df = DataFrame(x = rand(10), y = rand(10))
        @compile_workload begin
                t = scatter(df; x = :x, y = :y, mode = "markers")
                plot(t)
        end
end

end # module PlotlyDFTest

```

When I try using this package I get the following error:

```julia
julia> using PlotlyDFTest
Precompiling PlotlyDFTest
  ✗ PlotlyDFTest
  0 dependencies successfully precompiled in 3 seconds. 73 already precompiled.

ERROR: The following 1 direct dependency failed to precompile:

```

However if I just do the following in the REPL there’s no problem:

```julia
julia> using DataFrames, PlotlyJS

julia> df = DataFrame(x = rand(10), y = rand(10))
10×2 DataFrame

     │ Float64 Float64

julia> t = scatter(df; x = :x, y = :y, mode = "markers")
scatter with fields mode, type, x, and y

```

This as well:

```julia
julia> let
       using DataFrames, PlotlyJS
       df = DataFrame(x = rand(10), y = rand(10))
       t = scatter(df; x = :x, y = :y, mode = "markers")
       plot(t)
       end

```

I’m testing this in v"1.10.0-beta1" on x86\_64 but I also experienced the same error on v1.9
