This is not a lossless change because there is an additional span level.

Could we use some of the code here of dom api to remove this span ?

Then why not just continue using htmr?

The new CodeBlockRuntime also has an additional div wrapper.

@SoonIter In case that we've already included rehype related tools due to CodeBlockRuntime/shiki, I think we should use rehype-parse + hast-to-jsx-runtime instead, WDYT?
