Infix rule ignored

Hi!
I need to customize the tokenizer to correctly handle this text:

Experience with Node.js/Express and Python/Django.

I customized the infixes, but only Python/Django us tokenized correctly, while Node.js/Express is treated as a single token.

import os
import spacy
from spacy.tokenizer import Tokenizer

nlp = spacy.load('en_core_web_sm')

prefix_regex = spacy.util.compile_prefix_regex(nlp.Defaults.prefixes)

infixes = tuple([i for i in nlp.Defaults.infixes if i != '#'] + [r',', r'/', r'\(', r'\)', ])
infix_regex = spacy.util.compile_infix_regex(infixes)

suffix_regex = spacy.util.compile_suffix_regex(nlp.Defaults.suffixes)

tokenizer = Tokenizer(
    nlp.vocab,
    prefix_search=prefix_regex.search,
    suffix_search=suffix_regex.search,
    infix_finditer=infix_regex.finditer,
    token_match=None
)

nlp = spacy.blank('en')
nlp.tokenizer = tokenizer

nlp.to_disk('my-custom-model')

# Test
text = 'Experience with Node.js/Express and Python/Django.'

for t in nlp.tokenizer.explain(text):
    print(t)

'''
OUTPUT
('TOKEN', 'Experience')
('TOKEN', 'with')
('TOKEN_MATCH', 'Node.js/Express')
('TOKEN', 'and')
('TOKEN', 'Python')
('INFIX', '/')
('TOKEN', 'Django')
('SUFFIX', '.')
'''

How can I make the infix / to work correctly?
