Sometimes a minecart sound plays/subtitle shown when loading a world

I heard this sound sometimes when logging on servers in older versions, but I just had it happen on singleplayer. Basically, I'm not sure how to reproduce this, but very rarely when opening a world, you'll hear the 'minecart.base' sound. I'm really not sure how to reproduce it, but I put a video below of the issue in action. Maybe try to maybe make a world then duplicate it, then play on the copy, then delete the copy and redo. That's what I did and eventually it happened.
I'm not too sure but I think this glitch is much, much more common in the latest snapshot than in the past. In the past I believe I heard it probably only twice or three times, and I just had this glitch happen almost twice in a row.

I was lucky enough to get this rare glitch on video, here it is: https://youtu.be/qchGJDQlNys
(Please mind the long duration of the loading screen and the window being recorded on the wrong side. The recording software I use is laggy and buggy)

How to reproduce

1. Have subtitles enabled
2. Create world with seed -6781790025949582501
3. Observe the issue right after entering the world
