Source maps not mapping close parenthesis

[dsherret]

Describe the bug

It seems source maps aren't mapping close parenthesis. Is that expected?

See here how on the function declaration after the parameters it's not mapped and also after the arguments in the call expression.

This just recently surfaced in our test suite, but didn't before because previously the semi-colon was mapped, but now it's not (this screenshot is from before. This is no longer mapped):

This seems wrong or at least inconsistent in that example—open paren is mapped:

But not close paren:

Previously they were both mapped.
