Possible bug: 0 12 1-31 * 1 is parsed incorrectly

[MaxHam]

Hi, the expression 0 12 1-31 * 1 should output dates that match every day-of-month and day-of-week since both fields are not *, but it outputs the same as 0 12 * * 1 , which should only match the day-of-week, since day-of-month is *.

The output is:

• Mon, Sep 12, 2022, 14:00
• Mon, Sep 19, 2022, 14:00
• Mon, Sep 26, 2022, 14:00
• Mon, Oct 03, 2022, 14:00
• Mon, Oct 10, 2022, 14:00
• Mon, Oct 17, 2022, 14:00

On the other hand an expression like 0 12 1 * 0-6 triggers every day, while the expression 0 12 1 * * triggers only on the first day-of-month. I think this behaviour is the correct one and I am asking why the behaviour is asynchronous between day-of-week and day-of-month being either * or 1-31, 0-6.
