I mentioned in #9966 that I didn't find an inpainting controlnet for SD3.5 Large, and the only IP-Adapter available is for SD3.5 Large afaik, so we can't really test it properly if that's the case.

Thanks @guiyrt. As you pointed out we may be unable to test this due to incompatible checkpoint availability however as the code is all Copied from it should be ok and ready for potential future releases. Could you take a look at the Copied from check and run make fix-copies?
