id likers: invalid attributes in german localization

We faced an a11y issue while BITV examination (german wcag). In german localisation the id="likers" has some weird attributes:

• title (completely empty)
• gefällt
• mir"
• anzeigen"

I guess this has something to do with the quotation marks in the translation file. In xwiki-platform-core/xwiki-platform-like/xwiki-platform-like-ui/src/main/resources/XWiki/Like/LikeTranslations.de.xml I found only one matching pattern in line #44:

like.unlike.modal.viewLikersButton="Gefällt mir" anzeigen

In  xwiki-platform-core/xwiki-platform-like/xwiki-platform-like-ui/src/main/resources/XWiki/Like/LikeViewersMenuUIX.xml I found the line #170:

#submenuitem($doc.getURL('view','viewer=likers'), $services.localization.render('like.unlike.modal.viewLikersButton'), 'likers', '', 'heart')

I guess this creates the title attribute for id "likers" and the text after the <span class="fa fa-heart"></span>.

What doesn't exactly match: that bad attribute 'gefällt' starts with a lower case letter but in LikeTranslations.de.xml it's an upper case letter.

To make it more visible here an image:

We fixed it temporarily with a script:

// bei "Gefällt mir"-anzeigen im 3-Punkte-Menü sind die Anführungszeichen in den Attributen verkehrt gesetzt
try {
  let likers=document.querySelector("#likers");
  likers.removeAttribute('gefällt');
  likers.removeAttribute('mir"');
  likers.removeAttribute('anzeigen"');
  likers.setAttribute('title', '"Gefällt mir" anzeigen');
} catch (e) {
  console.log('Kein "gefällt mir"-anzeigen gefunden')
}
