The body text isn't wrapping within its parent in the React demo (for all 3 examples).. see Core vs React:

That's likely not an issue with this PR, but with the new docs. You can compare it against the preview that has the first doc change here. I'll add it to #1724 which is tracking the broken doc site styles.
