title: ReactJS _ NextJs - My console.log returns me: "onmozfullscreenchange is deprecated"
body: <p>I have searched in my folder but nowhere there is a "onmozfullscreenchange" defined. Maybe someone can explain us what that means? On <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=1504946" rel="nofollow noreferrer">Bugzilla</a> there is some obscure discussion like that, I think they talk about the browser and some patch but it have nothing to do with my code I think. </p>
  
  <p>I have updated my package but the warning still occurs,</p>
  
  <p>any hint would be great,
  thanks</p>
