Detail not working with Abstract Vectors, only with DataFrame.

[davibarreira]

For a 100x4 array containing my data, if I try to plot the following:

@vlplot(:line,x=df[:,1],y=df[:,2],color={df[:,3],type="q"},order ={field ="row", type="q"},detail={df[:,4],type="o"})

I get the following Warning:
WARN Dropping {"type":"o"} from channel "detail" since it does not contain any data field, datum, value, or signal.

And the "detail" is not applied. Note that even if I add the name "field", thus making

@vlplot(:line,x=df[:,1],y=df[:,2],color={df[:,3],type="q"},order ={field ="row", type="q"},detail={field=df[:,4],type="o"})

Then I don't get any warnings, but the "detail" is not added.
If instead I use a DataFrame:

@vlplot(data=df,:line,x=:x,y=:y,color={:z,type="q"},order ={field =:row, type=:q },detail={field="group",type="o"})

Then everything works properly.

So the reason this doesn't work is that I disabled it in 2e2dfce. I labeled that commit as "fixing some bug", but I don't remember what the bug was... But given that I explicitly fixed something there, I'm a bit nervous about undoing it again... Not sure what to think of this right now... Maybe one of the other contributors here has an idea why I might have done this in the past? And yes, I know what a ridiculous question that is ;)
