TL;DR
Glazed terracotta (and some other blocks) get placed backwards from how they look in the hand. It makes it unintuitive to place.
(arrow points backwards in hand but forwards in world, opposite of blocks like furnaces)
Background
Various blocks can be placed in multiple orientations based on the player's rotation (chests, pistons, etc). For most of these blocks, the side that will be facing the player when placed is positioned like so:
Facing towards the player in first-person
Facing away from the player (on the inner side) in third-person
On the right half of the GUI icon
Facing straight out in an item frame
This is illustrated in the following two images:[media][media]
The bug
Some blocks do not follow this convention for one or more models, resulting in unintuitive or confusing placement.
✔ = matches most blocks
❌ = affected by this issue
First person is most relevant since it defines your intuition for block placement, but I've included blocks that are unusual in third person for the sake of completeness.
Block | First Person | GUI | Third Person |
|---|---|---|---|
Glazed terracotta | ❌ 180° | ❌ 180° | ❌ 180° |
Observer (see note*) | ❌ 90° | ❌ 180° | ❌ 180° |
Piston/sticky piston | ❌ | ❌ | ❌ |
Fence gate | ❌ | ✔ | ✔ |
End portal frame | ❌ 90° | ✔ | ✔ |
Banner | ❌ 90° | ✔ | ✔ |
Command block | ❌ 90° | ✔ | ✔ |
Chiseled bookshelf | ❌ 90° | ✔ | ✔ |
Stonecutter | ❌ 90° | ✔ | ✔ |
Trapdoor | ❌ 90° | ✔ | ✔ |
Button | ❌ 90° | ✔ | ❌ |
Stairs | ✔ | ✔ | ❌ |
Skull | ✔ | ✔ | ❌ |
Chests | ✔ | ✔ | ❌ |
Anvil | ✔ | ❌ | ❌ |
Big Dripleaf | ❌ | ✔ | ❌ |
Small Dripleaf | ❌ | ✔ | ❌ |
Decorated Pot | ❌ | ✔ | ❌ |
Calibrated Sculk Sensor | ❌ | ✔ | ❌ |
Grindstone | ❌ | ✔ | ❌ |
Crafter | ❌ | ✔ | ✔ |
Vault | ❌ | ✔ | ✔ |
Attached are images of affected blocks in the contexts in which they appear inconsistent, with a before ("Vanilla") and after ("Fixed") image.
(* Rotating the observer in the GUI makes it look rather strange, so a more correct fix may be to alter its placement so that the "face" faces the player when placed instead of the back.)
One more thing
Blocks that "attach" to the face you click on (logs, shulker boxes...) follow a convention where the model is oriented vertically. However, jigsaw blocks do not follow this convention and are also confusing to place.

This affects the loom too. More info in MC-137761
As of 1.20.5 Release Candidate 2 there are a couple new blocks affected:
Crafter | ❌ | ✔ | ✔ |
Vault | ❌ | ✔ | ✔ |
|Crafter|(x)|(/)|(/)|
|Vault|(x)|(/)|(/)|Affects 1.21, 1.21.1, & 24w34a.
The barrel is also affected by this. This is the same case as the piston though and could be WAI:
Barrel | ❌ | ❌ | ❌ |
|Barrel|(x)|(x)|(x)|After reviewing the list I have made a few observations.
Correct me if I'm wrong but it seems that Buttons and Looms are correct in 3rd person
Grindstones are not correct at all. (item icon and third person are backwards and first person is sideways)
Fences don't look correct in 3rd person
Code for all changes:
|Fences|(/)|(/)|(x)|
|Grindstone|(x)|(x)|(x)|
|Button|(x)|(/)|(/)|
|Loom|(/)|(/)|(/)| (Remove from list)The loom was fixed with the fix of MC-137761. Thanks, I've removed it. I also want to add the number of degrees each model is off by. I added some, but got lazy and didn't finish, and I didn't distinguish between 90 and -90.
I’ve finally taken the time to look deeper into this issue and split it into individual reports, since every item is different.
Here are the new tickets, grouped by the cause:
Missing firstperson_righthand rotation:
End Portal Frame: MC-308294
Calibrated Sculk Sensor: MC-308296
Command Block: MC-308297
Jigsaw Block: MC-308297
Observer: MC-308298
Vault: MC-308299
Chiseled Bookshelf: MC-308300
Crafter: MC-308301
Dried Ghast: MC-308302
Trapdoor: MC-308305
Fence Gate: MC-308306
Stonecutter: MC-308307
Grindstone: MC-308308
Incorrect firstperson_righthand rotation:
Backwards model:
I have decided that the other items in this report (pistons, stairs, skulls, chests, anvil, shelf) look correct in first person and therefore there is no bug.
Also affects buttons and trapdoors as of 17w47a. Will update later.
