 Opted to modify firefox code to get any useful information out of it:
 
     if (IsSupported(GLFeature::robustness)) {
         const SymLoadStruct symbols[] = {
             { (PRFuncPtr*) &mSymbols.fGetGraphicsResetStatus, { "GetGraphicsResetStatus",
                                                                 "GetGraphicsResetStatusARB",
                                                                 "GetGraphicsResetStatusKHR",
                                                                 "GetGraphicsResetStatusEXT",
                                                                 nullptr } },
             END_SYMBOLS
         };
         if (fnLoadForFeature(symbols, GLFeature::robustness)) {
             const auto status = mSymbols.fGetGraphicsResetStatus();
             MOZ_ALWAYS_TRUE(!status);
 
 This assert fires.
