`AssertionError`s with differing items in dict of lists do not display properly when not running in verbose mode

• a detailed description of the bug or problem you are having
  when an assert statement fails where the values being compared are dicts of lists with 8 or more items in the list, it does not show what part of the list was different in the output.
• output of pip list from the virtual environment you are using
  not using pip
• pytest and operating system versions py
  pytest 8.0, windows 10/11
• minimal example if possible

def test_something():
    value1 = {"asdf": [1, 1, 1, 1, 1, 1, 1, 1]}
    value2 = {"asdf": [1, 1, 1, 1, 1, 1, 1, 2]}
    assert value1 == value2

AssertionError: assert {'asdf': [1, ...1, 1, 1, ...]} == {'asdf': [1, ...1, 1, 1, ...]}
  
  Differing items:
  {'asdf': [1, 1, 1, 1, 1, 1, ...]} != {'asdf': [1, 1, 1, 1, 1, 1, ...]}
  Use -v to get more diff

the truncated diff does not show what part was different. it should instead display something like:

  Differing items:
  {'asdf': [1, 1, 1, ...1, 1]} != {'asdf': [1, 1, 1, ...1, 2]}

Start with the provided test_something example under pytest 8.0 on Windows and compare its normal output with the -v output. Trace the assertion comparison and truncation path; done means the non-verbose Differing items section identifies the differing final list value instead of only showing ellipses.
