After debugging, this seems to happen only in sentry when we have an initial offset (e.g. t=<number> query param). Roughly what happens is:

• we inject some default css including noscript { display: none; }
• call play(offset)
• --> call applyEventsSynchronously
• ----> uses virtualDOM
• ------> does not copy over the styles that were injected
