Audio button not working with kana-only vocabulary in reviews

Might I recommend implementing the behavior of [Userscript] Review Audio Tweak 4 while you’re at it? Specifically, allowing audio to be played after answering a kanji-based vocab meaning question if the reading question has already been answered correctly. Many users like it as an extra way to reinforce the reading and its connection to the meaning.

As you can see by the #4 in the script title, this one has broken many times over the years, so I think making it a first class feature would be valuable.
