Describe the bug

1. There is no option to disallow empty values for number inputs
2. Attempting to set the field value (with a controlled input) using onBlur does not update the UI

As a result, if the user deletes all the content from a NumberInput via backspace and then also presses delete, the field can seemingly be left blank, even when this is not allowed and min/max values have been supplied.

This was my workaround:

          <Controller
            name={'cycleLengthInWeeks'}
            control={control}
            render={({ field }) => (
              <NumberInput
                clampBehavior={'strict'}
                label={'Cycle Length in Weeks'}
                min={1}
                max={52}
                value={field.value}
                onBlur={(blurAction) => {
                  blurAction.currentTarget.value = String(field.value);
                }}
                onChange={(value) =>
                  field.onChange(isNumber(value) && value > 0 ? value : 1)
                }
              />
            )}
          />
