Multiple Id's in aria-describedby yield an error

Reduced test-case

<div class="modalWindow" id="delete_service_1" role="alertdialog" aria-modal="true" aria-labelledby="dialog-header-1" aria-describedby="description-part-1-1 description-part-2-1">
    <div class="modalWindow__content">
        <h4 class="modalWindow__header" id="dialog-header-1">Dienst verwijderen</h4>
        <div class="modalWindow__main">
                <p id="description-part-1-1">Ben je zeker dat je jouw unieke gepseudonimiseerde eduId voor ORCID wil verwijderen en de toegang tot je gelinkte accounts wil herroepen?</p>
    <p id="description-part-2-1">Deze dienst zal je misschien niet meer herkennen de volgende keer je inlogt, waardoor al je persoonlijke data kan verloren zijn.</p>

            <div class="modalWindow__buttonRow">

Configuration

No special configuration

Expected result

No error to be shown, as both id's in the aria-describedby exist. A space-separated list of id's is allowed as a value, see https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/ARIA_Techniques/Using_the_aria-describedby_attribute
