Search overlay not closing after selecting item

[gabriele-ct]

If the user is on a certain page and uses the Algolia search functionality to search for any term that links to the same page, when he clicks the search result, the overlay doesn't disappear.

It happens on production using Algolia search. Here's a video: https://commercetools.slack.com/files/U020GRFMX8E/F07EKBKU7A9/docs_search_grey_overlay.gif

Steps to reproduce:

• Navigate to https://docs.commercetools.com/api/projects/inventory
• Click in the search box and write inventory add click on the Update Actions > Add Quantity item
• Observe

Expected result:

• The page scrolls to the relevant section
• The overlay disappears

Actual result:

• The page scrolls to the relevant section
• The overlay stays

We (ET) decided to do this for the Next.js app only
