Subtitle "entity.bee.loop" never shows up and subtitle "entity.bee.ambient" is unused

If you are around bees, you can constantly hear them buzzing. However, the buzzing sound's subtitle string subtitles.entity.bee.loop is not in the subtitles.

When the sound is played via /playsound, the subtitle shows properly.

Additionally, the translation string subtitles.entity.bee.ambient exists, but is unused, while it's also identical to subtitles.entity.bee.loop.
