exclude_regex_paths is not longer working with default threshold_to_diff_deeper

[wreggyl]

Describe the bug
The exclude_regex_paths is not working if the keys are different and would be filtered out. Only working if the threshold_to_diff_deeper is set to 0

To Reproduce
t1 = {'a': [1, 2, [3, {'foo1': 'bar'}]]}
t2 = {'a': [1, 2, [3, {'foo2': 'bar'}]]}
diff = deepdiff.DeepDiff(t1, t2, exclude_regex_paths="['foo.']")

Expected behavior
Diff is expected to be empty

OS, DeepDiff version and Python version (please complete the following information):

• OS: [MAC OS, Windows]
• Version [14.6.1, 11]
• Python Version [3.12, 3.9.2]
• DeepDiff Version [8.0.1]

Additional context
Example from:
https://zepworks.com/deepdiff/current/exclude_paths.html
diff = deepdiff.DeepDiff(t1, t2, exclude_regex_paths="['foo.']", threshold_to_diff_deeper=0) is working and produces empty diff

I face the same problem.
Regex comportement with exclude_regex_paths has completely changed. Exemples shown in official documentation are not working in Python 3.12
I'm using DeepDiff Version [8.4.2]

I face the same problem.

php_data = {"main_category":[{"class":3,"article_id":70518358,"ID":453},{"class":2,"article_id":70518358,"ID":175},{"class":1,"article_id":70518358,"ID":163}]}
go_data= {"main_category":[{"article_id":70518358,"ID":453},{"article_id":70518358,"ID":175},{"article_id":70518358,"ID":163}]}

diff = deepdiff.DeepDiff(php_data, go_data, exclude_regex_paths=r"root[main_category][\d+]['class']",
ignore_order=True)
diff return values_changed
