[webauthn] Exception handling in cryptoParameters processing needs to be clarified

bzbarsky has just created a new issue for 
https://github.com/w3c/webauthn:

== Exception handling in cryptoParameters processing needs to be 
clarified ==
The "normalizing an algorithm" steps called by 
https://w3c.github.io/webauthn/#dom-webauthentication-makecredential 
can throw exceptions of various sorts.  It _sounds_ like these 
exceptions do not cause `makeCredential` to throw the corresponding 
exception; instead the next entry in the list is considered.  But what
 happens to the exception?  Is it simply caught?   Is it reported 
(e.g. to the window's error event listeners and to the developer 
console)?  Something else?

This needs to be specified, since the exception is not just 
propagating out.
