[BUG] Overwriting locals_max_length and locals_max_string does not affect printed Traceback

[CollinHeist]

• I've checked docs and closed issues for possible solutions.
• I can't find my issue in the FAQ.

Describe the bug

Initializing a Traceback object with a non-default locals_max_length or locals_max_string does not affected the locals when printed. MRE below:

from rich.console import Console
from rich.traceback import Traceback

console = Console()

def bad_func():
    # Arbitrary local data which is longer than default max length
    from string import ascii_letters
    _locals = {k: k * 150 for k in ascii_letters}

    try:
        1 / 0
    except Exception:
        tb = Traceback(
            show_locals=True,locals_max_length=None, locals_max_string=None,
        )
        console.print(tb)
bad_func()

This prints the following traceback:

ZeroDivisionError: division by zero

Which, according to the docs, setting either limit to None should disable truncation and remove the ... and ... + 42.

The problem is not in the rich.pretty.traverse function, which implements this correctly, as can be seen by calling patching the function to hard-code in a non-default limit, which is then properly applied.
