Bug 96714 – [Forms] multiple fields time input UI should save/restore its value even if it has an empty field.

• Status: RESOLVED
• Resolution: FIXED
• Component: Forms

If user populates partial values into multiple fields time input UI, e.g. "--:12:-- AM". Back to a page navigation resets all fields empty unless all fields have value.

This behavior makes users to enter all fields again. So, we should save/restore all fields regardless field has value or not.

You need to increment the version number in FormCotroller.cpp formStateSignature() because this is an incompatible change.

> Source/WebCore/html/shadow/DateTimeFieldElements.cpp:146
> +        DateTimeNumericFieldElement::setValueAsInteger(hour12);

We need to do something for out-of-range values.
The hour12 value comes from a serialized state, and it might be corrupted.

> Source/WebCore/html/shadow/DateTimeFieldElements.cpp:156
> +            DateTimeNumericFieldElement::setValueAsInteger(hour12 == 12 ? 12 : hour12 + 12);

ditto.

> Source/WebCore/html/shadow/DateTimeFieldElements.cpp:158
> +            DateTimeNumericFieldElement::setValueAsInteger(hour12);

ditto.

> Source/WebCore/html/shadow/DateTimeFieldElements.cpp:209
> +        setValueAsInteger(dateTimeFieldsState.millisecond());

ditto.

> Source/WebCore/html/shadow/DateTimeFieldElements.cpp:247
> +        setValueAsInteger(dateTimeFieldsState.minute());

ditto.

> Source/WebCore/html/shadow/DateTimeFieldElements.cpp:285
> +        setValueAsInteger(dateTimeFieldsState.second());

ditto.

nit: the variable name should be fieldsState or something.

> Source/WebCore/html/shadow/DateTimeEditElement.cpp:414
> +void DateTimeEditElement::setValueAsDateTimeFieldsState(const DateTimeFieldsState& dateTimeFields, const DateComponents& dateForReadOnlyField)

ditto.  dateTiemFieldsState?
