Syntax highlighting problem for fenced code blocks

someone want to look into whether this might be an easy adjustment in whatever Jekyll thing is doing the highlighting?

[ashawley]

It is called Rouge, and there is a lexer for Scala here https://github.com/rouge-ruby/rouge/blob/master/lib/rouge/lexers/scala.rb

I believe Rouge was recently updated when Jekyll was updated in #1337.
