Looks like we need rehype-raw to prevent a breaking change for existing user rehype plugins. But rehype-raw strips out the node data intentionally (syntax-tree/hast-util-raw#13). Trying to write a rehype plugin to preserve it for code tagNames.

#5335 should fix this with an alternative approach. Rehydrating the data field requires double hast tree traversal regardless if you use a code block or not, so it doesn't feel worth the effort. The PR should be much simpler.
