TCK: Issue3020IT: testDelayNegative Fails

App Code: https://github.com/jakartaee/faces/blob/4.0.1/tck/faces22/ajax/src/main/webapp/issue3020Negative.xhtml#L35

Unit Test:
https://github.com/jakartaee/faces/blob/4.0.1/tck/faces22/ajax/src/test/java/ee/jakarta/tck/faces/test/servlet30/ajax/Issue3020IT.java#L49-L54

The test verifies that a delay on the f:ajax is a valid input.  The test uses "NaN" and the implementation is expected to throw an exception to stop the request from occurring.

Our RC2 code appears to be here: https://github.com/apache/myfaces/blob/89c747e85615e3f33265e664c8361789f38ea7db/api/src/main/javascript/META-INF/resources/myfaces/_impl/core/Impl.js#L311-L314

I've attached the TCK application (with Mojarra) to this issue.
