Doesn't include hiragana after kanji when hovering tofugu ruby spans

From https://www.tofugu.com/japanese/wa-and-ga/

If you take this block and hover the　食べたい then it only detects the kanji without the rest of the word.

The hiragana are a couple levels up from the kanji so it might be tricky.

Nevermind, it works when I tested it again just now.

What doesn't work is if there is hiragana after the rubied kanji then the full word isn't read. That's more common since the text nodes are in different elements.
