Bug: slice_dictionary yields duplicate chunks instead of slicing dictionary correctly

[anafalcao]

Expected Behaviour

slice_dictionary should yield consecutive chunks of dictionary items until the input dictionary is exhausted. Each chunk should contain up to chunk_size items without repetition.

Current Behaviour

The slice_dictionary helper currently does not slice dictionaries into chunks properly.
Because itertools.islice(data, chunk_size) always starts from the beginning of the dictionary, each iteration yields the same first chunk_size keys, resulting in duplicate chunks.

Code snippet

import itertools

def slice_dictionary(data: dict, chunk_size: int):
    for _ in range(0, len(data), chunk_size):
        yield {dict_key: data[dict_key] for dict_key in itertools.islice(data, chunk_size)}

data = {"k0": 0, "k1": 1, "k2": 2}
# actual   [{'k0': 0, 'k1': 1}, {'k0': 0, 'k1': 1}]
# expected [{'k0': 0, 'k1': 1}, {'k2': 2}]
print(list(slice_dictionary(data, 2)))
