Waterlogged Block found on Java

When I was snooping with the debug stick (enable a setting in settings "Options > Controls <Enable Creators' Tab [<ON>]", the tab was fine, and when I saw the name "Debug Stick," I was amazed, and I saw waterlogged for a tree and it sad true after I figured it out how to work it and then-) [,] the whole tree got in a mess I though of a barrier and it created a waterlog, please fix Minecraft with the waterlog. I even have a Screenshot of it, like I said, I hope Mojang or the workers of Minecraft now fix this. Note: And to anyone who knows why the villagers are like this? I found it on Demo, current snapshot too. I thought the code got a little leaked and there is a gap.
