You can jump through the first layer of leaves of small oak trees

If you walk into a tree(we (me and rowan42how)) were on a multiplayer game on 1.17),I discovered that I could walk through the bottom layer of the oak trees in my world.This might only be a problem which only happened to me (as it didn’t occur for rowan42how),we were still concerned though,as it may end up being exploited as an x-ray glitch in servers/competitive games.IMPORTANT EDIT:I didn’t use an elytra,and am not wearing one in the photos by rowan42how.Thanks ocelot for your reply,but it’s not a duplicate and I could just jump through the first block of leaves as I’d only just joined.I think this should be reported as a new thing,because I had searched for being able to jump through leaves,but that didn’t work.Any help would be appreciated! All I’m doing is trying to make Minecraft a better place for all!Thanks,and if you find one like this,I’m sorry but as you’ve read,I did search.
