Might be a browser issue, The console error is :
Refused to execute JavaScript URL because it violates the following Content Security Policy directive: "script-src 'unsafe-eval' assets-cdn.github.com". Either the 'unsafe-inline' keyword, a hash ('sha256-...'), or a nonce ('nonce-...') is required to enable inline execution.

Seems broken recently
Looks like the github GUI changed Now this script only align code box on the left .... without enlarging
