Kana found between two kanji produces furigana readings

[ahlec]

When adding furigana to a word with kana between two kanji (eg, 走り去る), the produced furigana includes the hiragana found between the two kanji (in the example, it produces 走り去[はしりさ]る).

Expected behavior: 走[はし]り去[さ]る (?)

[obynio]

This is mostly due to how MeCab handles the kanji and produce the reading. Nothing much we can do here since MeCab development appears to be stalled since a few years.
