Web server config not working for vHost Aliasdomain
short description
Web server configs (nginx / apache) cannot be selected when using vHost Aliasdomains. The dropdown is there but only contains the "-" entry. Using regular websites all expected Web Server Configs are there and selectable.
Currently the nginx (didn't tested with apache) is used from the parent. But the PHP configs ("required php snippets" from the web server config) are not applied.
correct behaviour
The dropdown should contain the configured Web Server Configs and also apply webserver AND php configs to the aliasdomains config files.
I believe this might be a regression, as I think it worked before.
