A bug in Vuetify or my mistake?

Question

Vue.js

I installed vue-cli, connected vuetify exactly according to the instructions, and wrote the same code as in the example from the documentation https://codepen.io/pen/?&editable=true&editors=101

But the problem is that in the example, the font size in the icons is 12px , and mine is 24px.
I looked through devtools, I saw that in my example, the styles that set the font size to 24px are below the styles that set 12px, and overwrite them accordingly, and in the example from the documentation, the order is reversed.
