I want to train my ipadapter in sd3. I noticed that joint_attention_kwargs is used in passing the parameters to AttentionProcessor (https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/transformers/transformer_sd3.py#L309). But it seems joint_attention_kwargs is not passed to transformer_blocks. Is my usage method wrong or this parameter has not been developed yet? Thank you!
