Checkout email input field keeps `aria-invalid='true'` attribute and value after succesful validation

[svossen]

Preconditions

I’m seeing this behavior on every Magento2 shop I tested, both in Firefox and Chrome. Even on fresh Magento installations. The specifications for the situation of the attached screenshots are:

• Magento Open Source 2.3.0
• Sample Data 100.3.*
• macOS Mojave 10.14.2
• PHP 7.1.25
• MySQL 5.7.24
• Firefox 66.0b12 (64-bit)

Steps to reproduce

1. Add product to cart
2. Go to checkout
3. Leave email input field empty
4. Validate form by going to the next step
5. Enter a valid email address
6. Validate again by blurring the input field or go to the next step

Expected result

After successful validation, the aria-invalid attribute should be removed or the value should be set to false.

Actual result

The checkout email input field keeps the aria-invalid='true' attribute and value after succesful email validation. The validation error message does gets hidden and the mage-error class does get removed and is replaced by valid. This situation will result in accessibility issues.
