Merge branch '22525-emoji-dropdown-shows-search-results-label-several-times' into 'master'

Fixed awards dropdown search text from repeating

## What does this MR do?

Thanks @zeiv for this!

>This fixes #20463 by adding the .emoji-search class to the "Search results" h5 element.  AwardsHandler.prototype.setupSearch() was trying to remove the element before creating a new one, but wasn't because the it was attempting to select it with the .emoji-search class, which wasn't being added.

## Are there points in the code the reviewer needs to double check?

>I don't believe so.

## Why was this MR needed?

>See #20463

_(and #22525)_
