[580] active class in router doesn't change to custom class

I have tried to change inline nuxt-link attribute active-class, and also router.linkActiveClass propertie in nuxt.config.js but neither works. It injects nuxt-link-active instead of my own defined active class (bootstrap active class)

Any one with this same issue?

Example here: https://glitch.com/edit/#!/handy-ostrich

PD: At the first try in "glitch.com" (with nuxt 0.10.3) it worked, but when I updated to 0.10.5 broke, and now, neither with 0.10.3 doesn't works

PD2: I edited the example in glitch.com and now router.linkActiveClass is working but active-class is not working
