Stepper | onFocus/onBlur not properly working

Extensions
1

Hey :waving_hand:, Noticed two issues on onFocus and onBlur:

Version:

"@shopify/ui-extensions": "2025.4.0",
"@shopify/ui-extensions-react": "2025.4.0",

Issue 1) onFocus and onBlur are not called:

import { Stepper } from '@shopify/ui-extensions-react/customer-account';

export const QuantitySelector = () => {
  return (
    <Stepper
      label="Qty"
      onFocus={() => {
        console.log('focus');
      }}
      onBlur={() => {
        console.log('blur');
      }}
    />
  );
};

Issue 2: onFocus is called, but onBlur is not:

import { Stepper } from '@shopify/ui-extensions-react/customer-account';
import { useState } from 'react';

export const QuantitySelector = () => {
  const [quantity, setQuantity] = useState(1);
  return (
    <Stepper
      label="Qty"
      name="quantity"
      min={1}
      value={quantity}
      error={quantity < 1 ? 'Minimum quantity is 1' : undefined}
      onChange={value => setQuantity(value ?? 1)}
      onFocus={() => {
        console.log('focus');
      }}
      onBlur={() => {
        console.log('blur');
      }}
    />
  );
};
