A handful of components (such as
minecraft:unbreakable
) work based on presence in the map - they do not store a boolean flag in the component. Using theget
methods have the side effect of adding the component to the builder map. So, if one of the presence-based components tries to be checked using one of those methods, then it will add them to the map even if that is not the intention. This PR aims to address that by adding a simplecontains
method that does not add the component and has no side effects.
