Pug: using a named slot without prop receiving, results in a compilation error

Do NOT ignore this template or your issue will have a very high chance to be closed without comment.

Describe the bug

I use <template lang="pug"> with the pug npm package in my project.

When I use a named slot from a component like this: template(v-slot:header), it can't compile anymore
But when I explicitly include the slot prop with it: template(v-slot:header="slotProp", it does work

This always worked in vue-cli projects so I'm curious if this can be fixed in vite
