data-emotion-css or data-emotion in SSR with extractCritical

[furai]

Hey,

I have a problem with understanding docs. It seems that when using criticalCss to extract styles into head in SSR scenario I should be using
<style data-emotion-css="cache_key and ids">{extracted styles}</style>

I'm using custom cache provider with my own key.

Later on when hydration happens it uses data-emotion-css attribute and not data-emotion.

Is that a correct assumption?

I'd appreciate any answers.

Cheers,
Furai
