Setting TimePicker with mouse or keyboard ignores min/max

Set up a TimePicker with a `min` and `max`. For example

            min={new Date(0, 0, 0, 0, 0)}
            max={new Date(0, 0, 0, 5, 0)}

Click on the text input to focus the 'hours' portion.

Roll the mouse scrollwheel up/down to change the hours.

You can 'scroll' past 5:00 and set the time to anything above the max.

You can also use the keyboard to enter any number outside the min/max.

Is this the expected behavior? Do we always have to add our own validation to check the min/max ourselves?

When the user steps out of the min/max range the component enters an invalid state


I think I figured out why I wasn't seeing this behavior. The above statement is not true when used in a `<Form>`.

A form stays valid when the time picker is outside it's min and max.

I had expected it to behave like the min and max for a NumericTextBox, where you can't select a value past the min and max, and if you keyboard enter a number too big or small, then on blur is automatically changes the value to fit the range.

example: https://stackblitz.com/edit/react-7vdrvp?file=app/main.jsx

So it seems when used as a Form field, we always need to do our own validation for the min and max.

Hello,  Jeff,

I consulted with one of the developers on the team, it seems that this is indeed the expected behavior. 

When the user steps out of the min/max range the component enters an invalid state, which is marked by the red border:


In case a full date is not set (for example, only the minutes are set), the value is null and the component does not perform any validation.
