Syntax Highlighting for Scala does not work when New Source browser beta feature enabled

With the new beta feature of "New Source Browser Experience" enabled, files with .scala aren't syntax highlighted. They are being displayed in plain text.

Adding this "?spa=0&fileviewer=file-view-default" to the end of the URL will then show the file as highlighted.
