[BUG] Selection of rows by label renders dataframe invalid

[gg-tmp]

Describe the bug
Selection of rows by label renders dataframe invalid

Steps/Code to reproduce bug

import cudf
import numpy as np

idx_1 = ["Hi", "Lo"]
idx_2 = ["I", "II", "III"]
idx = cudf.MultiIndex.from_product([idx_1, idx_2])

data_rand = np.random.uniform(0, 1, 3 * len(idx)).reshape(3,-1)
df = cudf.DataFrame(data_rand, index=["A", "B", "C"], columns=idx)

print(df.shape)
# (3, 6) -> OK

tmp = df.loc[["A", "B"]]

print(df.shape)
# (3,7) -> NOT OK

# print(df2) -> raises error
# "ValueError: rangeindex=True and multiindex=True cannot both be True."

print(cudf.__version__)
# 25.02.02

Expected behavior

1. The shape and content of df should not change
2. Printing of df should work
