Confirmed, not a bug. Hit F3+B and you will see that the hit box does not move when the chest opens. This is not an issue related to villagers. Apart from that, I don't believe Mojang has any future plans to fix this.
I believe this is the bug that adds the unintended "BUD" feature with pistions which is much loved.
Could it be you are using an outdated version of java? Send me a log if possible.
I would also move this to Minecraft: Java Edition.
This is controversial, I'm sure this is not an issue. There would be no reason to unless you were going to use it as a mechanic of some sorts.
Though, it would be nice to see a way to make certain unusable blocks to usable or vis-versa by attaching NBT data to them such has you can by the following command arguments:
CanPlaceOn:[]
CanDestroy:[]
It would be awesome to see something like:
CanUse:[]
