Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Note: this is a automatic message, so apologies if I miss something.

No answer, assuming no longer an issue.
