Search suggestions do not close when out of focus

1. Open search on any page.
2. Write at least 3 characters to get a suggestion.
3. Move and click somewhere else on the page to change focus.

Actual result:

• The search box is closed.
• The search suggestions stay open.

Expected result:

• I expect for the search box and suggestions to close/be hidden when I move out of focus.

Currently, the only way to hide the suggestions:

• when results are returned is to click on "hide suggestions"
• reopen the search and write 1-2 characters  (suggestions do no show for 0-2 characters).

When no suggestions are found, only the second option can be used.
