router.push with query parameters leads to localhost:8080/?categoryId=2. Why is there a slash before the query parameter?

I am using the router like this:

router.push({ name: 'home', query: { categoryId: category.id } })

And my route looks like this:

{
    path: '/',
    name: 'Home',
    component: Home
},

Is it normal for the URL to have a slash before the query parameter? Even if it doesn’t matter functionality wise, I feel like localhost:8080?categoryId=2 looks better than localhost:8080/?categoryId=2 and was wondering if I could somehow remove the slash?
