Variables are not replaced with the assigned values in web monitoring.

I have a host-macro {$PORTAL_PATH} with the value 'reports' which is assigned in the Scenario:

{path}={$PORTAL_PATH}

The URL of the Step:

http://{HOST.HOST}:8080/{path}/

Zabbix sends out this request:

GET /{path}/ HTTP/1.1
User-Agent: Mozilla/5.0 (X11; Linux i686; rv:8.0) Gecko/20100101 Firefox/8.0
Host: server3:8080
Accept: */*

This worked well with Zabbix 3.0, and stopped working after the upgrade to 3.2.
