All 3 of the spoilerboxes that are generated and injected via the userscript throw an error from the spoilerbox.ts resource in osu-web.
The basis of the change was to animate the spoilertag toggling and as a result, the injected HTML should include the newly required classes. Further details can be seen in the PR that introduced these changes here https://github.com/ppy/osu-web/pull/11375
