The wolf armor item displays a tooltip in the inventory showing the line "+11 Armor" when equipped. However since 24w09a this is no longer accurate as now the armor absorbs all damage from most sources without damaging the wolf until the armor breaks, instead of being only a certain reduction of damage, effectively acting like a shield.
This can cause confusion to players thinking it behaves like a diamond armor and it's probably an overlooked detail of the armor changes.
How to reproduce
Switch to creative.
Grab a wolf armor from the inventory.
Hover over the item.
Notice how the tooltip displays "+11 Armor".
Expected result
Either this line would not be displayed, or something different indicating this armor absorbs all damage would show on the tooltip.
Observed result
"+11 Armor" is displayed despite protecting 100% of damage.
Can confirm in 1.20.5, not sure why this wasn't prioritized for the full release.
