Markdown parsing errors when format_julia_builds=true or if context is specified

[jeremiedb]

2 bugs were identified in relation to markdown rendering.

1. If the Genie.config's watch is set to true, logging throws an error when parsing markdown files:

julia> ┌ Error: 2023-01-10 18:12:49 ErrorException("Parsing error for input occurred on line 14, offset: 6")
└ @ Genie.Renderer C:\Users\jerem\.julia\packages\Genie\1kq8p\src\Renderer.jl:388

The error can be reproduced by running the following app (dev branch): https://github.com/jeremiedb/GenieExperiments.jl/tree/dev

Then go to http://127.0.0.1:8000/md2

The actual config line causing the issue is: https://github.com/jeremiedb/GenieExperiments.jl/blob/303f9603eb6f8a9372f5f10adda62837e46d5c02/config/env/dev.jl#L12

2. In html function, if context is specified as = @__MODULE__, it results error with following stack trace and returns the 500 server error page:

julia> ┌ Error: 2023-01-10 18:14:55 ErrorException("Parsing error for input occurred on line 14, offset: 6")
└ @ Genie.Renderer C:\Users\jerem\.julia\packages\Genie\1kq8p\src\Renderer.jl:388

It can be reproduced by going to http://127.0.0.1:8000/md1 in the same GenieExperiments app.

The routes is specified as the following: https://github.com/jeremiedb/GenieExperiments.jl/blob/303f9603eb6f8a9372f5f10adda62837e46d5c02/routes.jl#L27-L33:

route("/md1") do
    html(
        path"views/markdown/blog1.jl.md",
        layout = path"layouts/markdown.jl.html",
        context = @__MODULE__,
    )
end

Which is somewhat puzzling since looking at html source code, it seems like context defaults to @__MODULE__ while the observed behavior is different when not specified as seen in the above /md2 example where rendering succeed (despite the parsing error).

I think the watch config option was the wrong diagnosis. It actually looks like it's format_julia_builds = true that results in MD parsing error, sorry about that.
