keep the indentation.

We should add an enum traits for this somewhere so we don't have to use decodeEnum.

This looks like it might be wrong.  The encoder encodes a DataReference, and this is decoding a std::optional<DataReference>.  That doesn't match.

I am not sure.
The enumeration is not in WebCore code, it might be easy to miss a change in the enumeration and not update the type trait.
Since it is not an enum class, I am also not sure there is a way to catch this issue through compilation error.

Ah, right!
Seems like an easy trap when mixing the legacy/new decoders.
