Unusual Sand Mining Animation, Sound and Particle Glitch

I was playing Minecraft Java Edition 26.3 in a singleplayer world. While mining sand, I suddenly noticed something strange.

The mining animation, sound, and particles started appearing together in an unusual way on the same sand block.

I could still break the sand block normally. After I clicked normally once, the glitch disappeared and everything went back to normal.

This was the first time I had seen this glitch. I also recorded a video of it.

I don't know how to make this glitch happen again.
