I dont know if this behavior is intended or not, but it was better how it was before if that is possible.

I think this issue is affecting doors as well. I saw a revert commit which will be in the next Rust update.

It is still a thing.  It is very easy to accidentally unlock while riding horse.  So this is a facepunch issue?

It must be due to the Rust changes. It's client side so I doubt there's anything we can do.
