Sorry, I was confused. You are doing the right thing.

The core problem would be that CodeGeneratorJS.pm does not yet implement non-custom named getters. Currently, no matter if it is [NamedGetter] or [CustomNamedGetter], we need to write custom bindings to WebCore/bindings/js/JS*Custom.cpp. And your patch is trying to avoid the custom bindings (only) for HTMLPropertiesCollection... right? In that case, hard-coding "HTMLPropertiesCollection" would make sense as a first step. (Eventually we should fix CodeGeneratorJS.pm so that it generates the bindings code automatically for [NamedGetter].)
