/**
 * @assertion Let s1,...,sn be those try statements that are both enclosed in
 * sE and that enclose sc, and that have a finally clause. Lastly, let fj be
 * the finally clause of sj, 1 <= j <= n. Executing sc first executes f1,...,fn
 * in innermost-clause-first order. Then, if sE is a case clause, control is
 * transferred to the case clause. Otherwise, sE is necessarily a loop and
 * execution resumes after the last statement in the loop body.

 * @description Checks that the execution of "continue;" statement transfers
 * control to the innermost enclosing asynchronous for-in statement with the
 * appropriate label and that all finally clauses between them are executed
 * in the innermost-clause-first order.
