Using an item while looking at an entity is no longer possible

Please add some of these to the Affected Items:

• Potions

• Lingering potions (Same as splash potions)

• Bottle o' Enchanting

• Armor (Prevents players from equipping)

This issue may have "temporarily fixed" the issue MC-141494 as the items are no longer used. Though if this issue is fixed, the issue MC-141494 would return.

Confirmed in 19w38a and 19w38b.

This issue appears to be from the "startUseItem" (using 19w39a obfuscation map names for research) method in Minecraft class.

Snippet:

switch (this.hitResult.getType()) {
                    case ENTITY: {
                        EntityHitResult entityHitResult_1 = (EntityHitResult)this.hitResult;
                        Entity entity_1 = entityHitResult_1.getEntity();
                        if (this.gameMode.interactAt(this.player, entity_1, entityHitResult_1, interactionHand_1) == InteractionResult.SUCCESS || this.gameMode.interact(this.player, entity_1, interactionHand_1) == InteractionResult.SUCCESS) {
                            this.player.swing(interactionHand_1);
                        }
                        return; // This forces to skip item use logic; compare to block one below
                    }
                    case BLOCK: {
                        BlockHitResult blockHitResult_1 = (BlockHitResult)this.hitResult;
                        int int_1 = itemStack_1.getCount();
                        InteractionResult interactionResult_1 = this.gameMode.useItemOn(this.player, this.level, interactionHand_1, blockHitResult_1);
                        if (interactionResult_1 == InteractionResult.SUCCESS) {
                            this.player.swing(interactionHand_1);
                            if (!itemStack_1.isEmpty() && (itemStack_1.getCount() != int_1 || this.gameMode.hasInfiniteItems())) {
                                this.gameRenderer.itemInHandRenderer.itemUsed(interactionHand_1);
                            }
                            return;
                        }
                        if (interactionResult_1 != InteractionResult.FAIL) break;
                        return;
                    }
                }

As you can see, the entity block forces to skip the logic for item interaction even though two types of entity interactions may request to "PASS" instead of "FAIL".

Suggested:

case ENTITY: {
                        EntityHitResult entityHitResult_1 = (EntityHitResult)this.hitResult;
                        Entity entity_1 = entityHitResult_1.getEntity();
                        InteractionResult result1 = this.gameMode.interactAt(this.player, entity_1, entityHitResult_1, interactionHand_1);
                        InteractionResult result2;
                        if (result1 == InteractionResult.SUCCESS || (result2 = this.gameMode.interact(this.player, entity_1, interactionHand_1)) == InteractionResult.SUCCESS) {
                            this.player.swing(interactionHand_1);
                        }
                        if (result1 == InteractionResult.PASS && result2 == InteractionResult.PASS) {
                            break; // Continue to item use logic
                        }
                        return;
                    }

This also causes the Zombie Doctor advancement to be impossible

That I cannot confirm. You just cannot look directly at the zombie villager while curing it, but you can throw a potion of weakness at it through other means. Feeding it a golden apple works as well.
