search_dates cannot find complete date

This simple example

text = 'Il giorno martedì 23 aprile 2019'

for chunk, date in search_dates(text, languages=['it'], settings={'DATE_ORDER': 'DMY'}):
        print(chunk)

prints three separate chunks:

martedì
aprile
2019

none of which is a complete date. For some reason it fails to recognize martedì 23 aprile 2019 as a single chunk. Removing Il giorno (the day) from the beginning of the sentence makes it parse correctly for some reason

Running on Mac OSX with

bash-3.2$ LOCALE
LANG="it_IT.UTF-8"
LC_COLLATE="it_IT.UTF-8"
LC_CTYPE="it_IT.UTF-8"
LC_MESSAGES="it_IT.UTF-8"
LC_MONETARY="it_IT.UTF-8"
LC_NUMERIC="it_IT.UTF-8"
LC_TIME="it_IT.UTF-8"
LC_ALL=

Start by reproducing the shown search_dates call with the Italian text and DATE_ORDER set to DMY. Trace the date-language parsing path responsible for combining the weekday, day, month, and year; done means the complete phrase is returned as one date chunk without breaking the existing example.
