Whitespace around < > in Web IDL is unusual

[foolip]

I've seen no other spec do this, and I found it not great for readability.

[equalsJeffH]

what the submitter was getting at is that we write our two promises in the webauthn IDL like so...

interface WebAuthentication {
    Promise < ScopedCredentialInfo > makeCredential (...);
    Promise < WebAuthnAssertion > getAssertion (...);
};

and what they are simply suggesting is..

interface WebAuthentication {
    Promise<ScopedCredentialInfo> makeCredential (...);
    Promise<WebAuthnAssertion>    getAssertion (...);
};

..as done, e.g., here..

interface PushManager {
    Promise<PushSubscription>    subscribe (optional PushSubscriptionOptions options);
    Promise<PushSubscription?>   getSubscription ();
    Promise<PushPermissionState> permissionState (optional PushSubscriptionOptions options);
};

..and throughout..

..as well as other W3C specs. this is trivial we should do it.

Yes, @equalsJeffH has it right.

Maybe also omit the space before (

If you use <xmp> instead of <pre>, you won't have to escape the <s. However, speced/bikeshed#933.
