[web-bluetooth] [[BackingMap]] manipulation is underdefined

bzbarsky has just created a new issue for 
https://github.com/WebBluetoothCG/web-bluetooth:

== [[BackingMap]] manipulation is underdefined ==
The spec has things like:

>  Add a mapping from code to new DataView(bytes) in 
event.manufacturerData.[[BackingMap]]. 

What does that mean?  Is it doing 
`event.manufacturerData.[[BackingMap]].set(code, new DataView(bytes)` 
using whatever the current value of `%MapPrototype%.set` is?  Or is it
 using the default value of `%MapPrototype%.set`?  Or something else?
