[These lines are in question](https://github.com/Mottie/GitHub-userscripts/commit/b8830e754c1a1d9fdd3a7ffc07487cef6b56ba51#diff-be55d55f33e883538d4369f2b03f4db8R31-R32) This single declaration allows `overflow` on _all_ codeblocks, such as on [this page](https://github.com/tc39/proposal-nullish-coalescing) (at least on a 1080 display).  What is the intent of this CSS? I've currently disabled this userscript due to this issue.
