In the last month or so I'm having an issue where using autofill multiple times on a web form causes some of the autofilled inputs to disappear. For example, if I autofill my contact info first, when I go to autofill my payment information, my contact info disappears. If I try to re-autofill my contact info, then my payment info disappears. The lost autofill inputs still leave behind yellow boxes as if still containing the autofill text, but the boxes are empty and submitting forms like this will fail, so I'm certain the autofilled information is being removed and not simply going invisible or something.
