Vue Router Child, Trailing slash

Is is it normal behavior for Vue to add a trailing slash to the default child subroute?

For example:

URL

Result:
/#/user/test/

Link

<router-link :to="{ name: 'user', params: { username: 'test' } }">Test User Overview</router-link>

Routes

routes: [
     {
        path: '/user/:username',
        component: User,
        children: [
            {
                path: '',
                name: 'user',
                component: UserOverview
            },
            {
                path: 'stats',
                name: 'user.stats',
                component: UserStats
            }
        ]
    }
]

I would expect the user link to have the path specified by its parent, meaning without a trailing slash. Like this: /#/user/test. If its normal behavior, can I somehow prevent it?
