From the description it sounds like a very rapidly moving target :)
@Munter We have an upgrade path to jsdom 11, including a feature that I got to work the other day (map scripts and stylesheets that originally occurred inline in HTML back to the location in that HTML): assetgraph/assetgraph#742
It's still blocked on killing node.js 4 support and sorting out the unexpected-dom issues
@Munter Any objections against assetgraph/assetgraph#747 ?
I found out that WSB publishes some text components as divs that have have white-space: pre-wrap applied via an external stylesheet, which html-minifier of course doesn't detect. That's why I need some knobs to customize the options.
Seemed like a good occasion to get rid of our own extra HTML minification step.
