This "Logstone" mechanic is very unintuitive. It only works in 1.20+ and on overworld trees only. Mojang Changed the code responsible for "leafstone": Leaves previously had a tag for their distance to a log that started at 1 and went up to 5 or something. But in 1.20, the leaves distance tag was altered and made logs part of that tag, where logs are now given the distance tag and it's set to 0. When a tree grows and its bounding box interferes with another pre placed log, the tag is kinda reset or something, and that creates a shape update, which lets observers see a change on logs despite the fact they haven't changed visually. At least, That's what I've been told by a guy who said they read the code, and the theory works with in game practice, so I assume it is correct. (To my understanding, the shape update is due to a change in the distance tag on the log. I can't read code.)
Personally, I would like this mechanic to stay, BUT TO BE CONSISTENT WITH NETHER TREES. Currently, nether trees adhere to the current "leafstone" mechanic where nether tree stems interact with leaves just the same as overworld trees, but they don't change their log distance tag to cause a shape update when a nether tree is grown within the required tree bounding box. I would like nether trees to adopt this mechanic, if it is deemed to be a voluntary game mechanic (For the sake of consistence and parity).
If the mechanic is deemed to indeed be a bug and get fixed, pre-placed logs shouldn't create a shape update when a tree is grown next to them.
