Dear all, We noticed that for URL https://mediapart.fr/en/journal/international/160322/exiled-russian-oligarch-sergei-pugachev-putin-s-junta-and-why-ukraine-marks-its-downfall?_locale=en&onglet=full the canonical URL is html-escaped: https://www.mediapart.fr/journal/international/160322/exiled-russian-oligarch-sergei-pugachev-putin-s-junta-and-why-ukraine-marks-its-downfall?_locale=en&onglet=full with & instead of & URL validators consider this url as invalid, because query contains ";" symbol. It seems to be a bug, could you check why it happens on your side and potentially fix it? Thank you very much!
