First time attempting to contribute, so bare with me please if i've missed anything or done anything wrong.
But I noticed this was merged ( #23101 ) so in addition, thought it would make sense to pre-cache those main assets.
Also not too sure how it works but I think Jekyll is serving/parsing the markdown doc files dynamically. It would be a cool idea if we could maybe get them to static html files? That way we can have offline support with this too!

Also ran grunt test and everything passed fine.
