Does anyone know what kind of syntax highlighter (and what theme, if it has any) does Firefox Quantum (v57+) use in it's Inspector panel of their developer tools?

I believe it was introduced with their new Photon UI, but I'm not sure whether it's just an updated code coloring theme or a totally new coloring processor.

As far as I know, the general tree view within the Firefox DevTools Inspector is developed by Mozilla. Though the editor used when editing a node (context menu > Edit As HTML) is CodeMirror, which is also used in other parts of the DevTools like the Debugger.

The theme is self-created to fit to the Photon layout.
