Yup. Soaking plastic in any bleach solution is not a great idea. Plastic actually absorbs the bleach. I personally avoid using bleach on anything, whether or not it is porous and use vinegar/peroxide, dissoap, etc. But I would strongly discourage anyone that does use bleach in their regular cleaning routine to avoid using it on anything porous.
