Dyed bundles are not able to be washed through a water cauldron

There are many different items that can be dyed in minecraft, and are able to get washed with a cauldron. For example, a shulker box can be dyed, but if you want to make it the original color again, you can right click it on a cauldron with water inside and it will wash the color away. I think this should be the case with the new bundles.
