Search dropdown unable to close after performing search

Summary

The top nav search's dropdown menu is unable to close after performing a search.

Steps to reproduce

1. Type in a query into the search bar
2. Click anywhere outside of the menu
3. Observe that the search input blurs, but the dropdown menu remains displayed

What is the expected correct behavior?

Dropdown menu should hide after clicking away, which works correctly if you focus and blur the search input without searching for anything.

Relevant logs and/or screenshots

Possible fixes

Probably an event binding issue in search_autocomplete.js preventing the dropdown menu from hiding itself.
