The Ubuntu 20.04 bot is failing with the following error: ``` /home/buildbot/worker/GTK-Linux-64-bit-Release-Ubuntu-2004-Build/build/Source/WebCore/css/StyleColor.h:53:50: error: ‘bool WebCore::CurrentColor::operator==(const WebCore::CurrentColor&) const’ cannot be defaulted 53 | bool operator==(const CurrentColor&) const = default; | ^~~~~~~ /home/buildbot/worker/GTK-Linux-64-bit-Release-Ubuntu-2004-Build/build/Source/WebCore/css/StyleColor.h:78:48: error: ‘bool WebCore::StyleColor::operator==(const WebCore::StyleColor&) const’ cannot be defaulted 78 | bool operator==(const StyleColor&) const = default; | ^~~~~~~ /home/buildbot/worker/GTK-Linux-64-bit-Release-Ubuntu-2004-Build/build/Source/WebCore/platform/text/TextFlags.h:166:65: error: ‘bool WebCore::FontVariantAlternatesNormal::operator==(const WebCore::FontVariantAlternatesNormal&) const’ cannot be defaulted 166 | bool operator==(const FontVariantAlternatesNormal&) const = default; | ^~~~~~~ /home/buildbot/worker/GTK-Linux-64-bit-Release-Ubuntu-2004-Build/build/Source/WebCore/platform/text/TextFlags.h:170:65: error: ‘bool WebCore::FontVariantAlternatesValues::operator==(const WebCore::FontVariantAlternatesValues&) const’ cannot be defaulted 170 | bool operator==(const FontVariantAlternatesValues&) const = default; | ^~~~~~~ /home/buildbot/worker/GTK-Linux-64-bit-Release-Ubuntu-2004-Build/build/Source/WebCore/platform/text/TextFlags.h:187:59: error: ‘bool WebCore::FontVariantAlternates::operator==(const WebCore::FontVariantAlternates&) const’ cannot be defaulted 187 | bool operator==(const FontVariantAlternates&) const = default; | ^~~~~~~ ``` Ubuntu 20.04 uses GCC9.3 It seems this version doesn't support default initialiaation of `operator==`. Also `operator!=` needs explicity definition.
