           Summary: [GTK][WPE] fast/css/calc-parsing.html test fails for
                    the hypot() function
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: CSS

          Reporter: agoldmints at igalia.com

Some of the hypot() subtests are failing on GTK and WPE, though interestingly not all the GTK and WPE bots. In particular, certain cases that should be errors are instead being parsed successfully:
