[THIS BUG WAS ONLY TESTED IN DARK OAK PLANKS IN VERSION 1.17.1, THIS POST WILL BE UPDATED AS I TEST IT MORE]

Hello! I was doing a creative build when i realized that yellow particled showed up when I fell in dark oak planks. I thought this could be an OptiFine/Resource Pack problem, since i usually play with this two, but i entered in Vanilla Minecraft 1.17.1 without any resource packs/data packs (anything, in general) and the problem was still there. This only happens sometimes though, because when i tested it more I realized that, in the same decimal coordinates (this is not shown in the video below) particles just didn't show.

I am posting a video that, hopefully, will serve as a proof and as a tutorial to replicate this issue. Hope this is helpful!

(The video is too big, so I am posting a YouTube link: https://youtu.be/_8kCNUv0s2o )
