Plugin Highlight horizontal srcoll

Good Day.

I’m using the Lingonberry v1.1.0 theme with the plug-in Highlight 1.3.2 (Grav v 1.3.7).

I have a long line of code, and would like the block that it’s in to scroll horizontally. However, it is wrapping at whitespace. I’ve tried to put the code in back-tics, tried 4 space indent, tried pre-tag, tried nowrap-tag, and have tried messing with the generated css in the Chrome debugger all to no avail.

Any ideas?
