Mines dissapear right after the receptors

This does not happen on 5.0.7, but I noticed that in 5.0.12 (and probably others), mines that don't get pressed disappear quickly after passing the receptors. This can be seen easily when the speed is 1x or 1.5x on songs with a low BPM.

It doesn't affect gameplay whatsoever, but it looks odd. Doesn't happen with regular notes though.

Is it a normal thing on recent versions or a bug that probably wasn't noticed before?

Mines are hidden so that the judgment system doesn't repeatedly spam the avoid judgment every frame until the next note.
