It would be surprising if JSON.parse() accepted a BOM, since it
doesn't take bytes as input.

However, XHR's responseType = "json" exercises browsers in a way where
the input is bytes from the network. From the perspective of JSON
support in XHR,

didn't reach the es-discuss part of this thread previously) applies.
