Interaction does not work in preview

[dgrachov]

Reproduction steps:

• Install project
• Run sourcey dev

Expected behavior:

Preview/dev server to display the documentation exactly how it is going to be presented after being built

Actual behavior:

No interaction works on the website. Scrollspy, search, drop-downs, etc.
