dark code syntax themes are not "dark"

[rmflight]

I went to the trouble of figuring out a dark theme for my distill blog, and I selected "breezedark" as the code theme, which according to this page should have a dark background.

However, in this screenshot you can see that the dark background seems to get overwritten, and it's a white background. It seems to me if the user specifies a dark syntax highlighting, that it should "just work".

This happens because distill is setting this CSS rule https://github.com/rstudio/distill/blob/570dcdbd406b87c507a63bf04f06f1808d1c28e9/inst/rmarkdown/templates/distill_article/resources/distill.html#L147-L149 which will overwrite the one set by the syntax highlighter

div.sourceCode {
    color: #cfcfc2;
    background-color: #232629;
}

This background white rule is hardcoded and does not depend on syntax highlight theme for now.

I believe this issue is related to https://github.com/rstudio/distill/issues/272

Also, it could be improve if theming would allow to modify this backgound color: https://rstudio.github.io/distill/website.html#theming which I don't think works today.

It is probably related to the other, in that setting the background color on posts seems to require at least a re-render of the site for the new CSS rules to be included.

Well, I've added those colors into my theme.css file, but it does make switching syntax highlighting themes a pain.
