Isn't this the classic bidi brackets problem? The 【 is assumed to belong to the base level because it's bidi neutral, but the 】 is assumed to be part of the LTR text, so they end up in different isolating runs. I don't think there's anything special about Japanese here. The same happens for () brackets and English text.
