Steps to Reproduce

configure a client side error handler e.g. in zk.xml

    <client-config>
        <error-reload>
            <device-type>ajax</device-type>
            <error-code>403</error-code>
            <reload-uri>/login</reload-uri>
        </error-reload>
    </client-config>

respond with 403 to an /zkau request (e.g. in a servlet filter handling authentication)
or respond a 403 from a zul file

<zk>
    <button onClick="execution.getNativeRequest().sendError(403);execution.setVoided();"/>
</zk>

Current Result

the client engine stops -> keeps showing the processing animation

Expected Result

the configured reload-uri should be triggered

Debug Information

the error handling code is not executed, the response.status.ok is false
