<SmartBreadcrumb /> does not show loading bar when clicking links

[BD103]

Switching pages by clicking a link through <SmartBreadcrumb /> does not use <NuxtLink />, and so does not show the loading bar added in f1249a0.

I thought I would be able to wrap an <NBreadcrumbItem /> in a <NuxtLink />, but it messes up formatting.

<template>
    <NBreadcrumb>
        <NuxtLink v-for="partIdx in routes.length" :key="partIdx" :href="routes.slice(0, partIdx).map(x => x[1]).join('')">
            <NBreadcrumbItem>
                {{ routes[partIdx - 1][0] }}
            </NBreadcrumbItem>
        </NuxtLink>
    </NBreadcrumb>
