It looks like most other pipelines such as Flux 2 use the following callback_kwargs pattern instead of a dict comprehension:

diffusers/src/diffusers/pipelines/flux2/pipeline_flux2.py

Lines 996 to 999 in 82f175e

	callback_kwargs = {}
	for k in callback_on_step_end_tensor_inputs:
	callback_kwargs[k] = locals()[k]
	callback_outputs = callback_on_step_end(self, i, t, callback_kwargs)

If I change the Ideogram 4 pipeline to use the above pattern, the test passes locally for me. So I think we should probably fix this in src/diffusers/pipelines/ideogram4/pipeline_ideogram4.py, then unskip this test (as well as test_callback_cfg below, which also passes after the change).
