11938	Small issue with {X.tag} in MapCSS	naoliv	team	"With the following test:

{{{
#!mapcss
*[aeroway = aerodrome] ∈ *[aeroway = aerodrome] {
          throwWarning: tr(""{0} inside {1}"", ""{1.tag}"", ""{0.tag}"");
}
}}}

We can see a message like `null inside aeroway=aerodrome` when validating.

Is it possible to support the `{X.tag}` in examples like this?
