You can't combine Infinity and Mending on a bow. That is logic because the new change. But you it is also impossible in Creative mode. While it is possible to put depth strider on an iron block (for example) or a bow. This is impossible in Survival. So it would be logical to be able to put any enchantment on a item in creative, also infinity and mending.

Works As Intended: Infinity and Mending are incompatible with each other, not with a tool. So, this is the same as putting Fortune and Silk Touch on a pickaxe, which is impossible both in creative and survival.
