Grafana Variable doesn't work at filter of hosts

[powerpower2005]

Describe the bug

1. Create Custom Variable named Server
2. Key:Value
3. front : /web.*/
4. Put the variable into Hosts section of Zabbix Query
5. It doesn't work as filter

Expected behavior
A clear and concise description of what you expected to happen.

I want the variable replaced with this value "/web.*/" literally.

But, I find out a kind of string in the Query Inspector
filter:"\/.web*\/"

I want to have variable to filter hosts, I don't want to choose host that I want to monitor in.

Variable as Zabbix Query can't do what I want.

I want to control hosts with regex(variable) in zabbix datasource.
