Summary Consider MasqueradesAsUndefinedObjectType

Reported 2018-06-01 05:16:10 PDT

MasqueradesAsUndefined is crazy feature, 1. It is introduced for backward compatibility of `if (document.all)` thingy. It is unlikely that MasqueradesAsUndefined objects increases 2. MasqueradesAsUndefined is only used for HTMLAllCollection right now 3. HTMLAllCollection is ObjectType So, what do we think of folding this information into JSType, and free up MasqueradesAsUndefined TypeInfo flag space? We can introduce MasqueradesAsUndefinedObjectType for HTMLAllCollection.
