If the search string doesn't change, the inline search doesn't clear the existing results, it just appends the new results to the existing list, giving duplicates.

To reproduce:

• Load https://beta.musicbrainz.org/artist/create and focus the area search
• Enter a search string, e.g. "japan"
• Press space then backspace

The expected result would be one entry for Japan, the actual result is two (or more, if you do it repeatedly)

Alternatively:

• Load https://beta.musicbrainz.org/release-group/create and focus the artist search
• Enter a search string, e.g. "test"
• Press space then backspace

Expected result would be one set of search results for "test", the actual result is two identical sets one after the other (or more, if you do it repeatedly)
