[Broken Website] MuseDash.moe cannot load leaderboards

[kikones34]

Prerequisites

• I searched for any existing report about this website issue to avoid opening a duplicate.
• I can reproduce this website issue in a new, unmodified web browser profile with Dark Reader installed as the only extension.

Website Issue Description

The dynamically loaded leaderboards never load and a JS exception is thrown, which doesn't occur with Dark Reader disabled.

Note that this website has a dark theme by default, so I opened a PR to include it in the dark sites list (#12717). This will prevent the website from breaking since Dark Reader will be disabled by default.

Either way, the issue may be worth to look into, since it could also affect other sites or may reveal a bug in Dark Reader.
