So the old path

<script src="../bower_components/leaflet/dist/leaflet.js"></script> is now at

<script src="../bower_components/leaflet/leaflet.js"></script>

as well as the css.

<link rel="stylesheet" href="../bower_components/leaflet/dist/leaflet.css" />

<link rel="stylesheet" href="../bower_components/leaflet/leaflet.css" />

This might be reverted to dist depending on what leaflet does about the bower situation. See #851

Leaflet 1.x still dist folder as distribution release.
