Describe the bug

When trying to add an artist to a song on the song addition page, the artist list glitches out and disappears.

To Reproduce

Steps to reproduce the behavior:

1. Go to https://vocadb.net/Song/Create
2. Paste the song link (for example: "https://www.nicovideo.jp/watch/sm31606995")
3. Type the artist name into the artist selection field (for example: "Hatsune Miku")
4. See the artist list disappearing after a short time

Expected behavior

I expected the artist selection list to stay so that I can choose the artist from the list.

Results:
After testing the bug on different browsers with the help of different user, I came to the following conclusion:

The bug occurs:

• Firefox (tested by Kesera and andreoda)
• Firefox incognito mode (tested by andreoda)
• Safari (tested by Xarion)

The bug does not occur:

• Safari incognito mode (tested by Xarion)
• Chrome (tested by minu and Rainshaft)
• Chrome incognito mode (tested by Rainshaft)
• Edge (tested by Rainshaft)
• Edge incognito mode (tested by Rainshaft)

About the results:

1. The bug seems to occur "sometimes", not always.
2. When the bug occurs, the artist list holds up to 1 second or less before it disappears.
3. The browser console doesn't seem to give any errors related to the bug.
4. The bug was also tested after clearing the browser cache and cookies.

I couldn't find a "clear" pattern to when this occurs.

Reproduced the bug and checked the syslog, but it does not seem to have any information about it.

Further context:

When adding songs, after editing the title field, the system checks for duplicates

When that request gets a respond, the artist selection dropdown gets automatically refreshed/closed.

This issue will be fixed once #853 is completed. If we migrate to mantine (as currently planned), we will use the mantine autocomplete.
