CVV code fields are not being excluded from auto-fill saved form fields

I was quite surprised today when I was filling out a credit card form when I clicked into the CVV form field and the correct CVV code to my card popped up in the browser auto-fill.
I would expect the browser to have blocks in place to not store the CVV code from any credit card, since all credit card regulations specifically prohibit storing CVV codes in any way.

May depend on the form, if identified as a CVC code (it shouldn’t save) or if the field just an numeric field. Which company payment form details saved your CVC details?

Also your details are saved here: brave://settings/payments
