Weird broadcasted form of multi symbols of calendar module.

[eouia]

I remember it was not so, but multiple symbols are broadcasted weirdly at some point.

When I set some symbols in a calendar like this;

symbol: ["file", "calendar"],

The expected broadcasted data(And the historical format what I remember) would be like this; (with defaultSymbolClassName)

symbol: ["fa fa-fw fa-file", "fa fa-fw fa-calendar"],
// Array(2)

Bur really broadcasted would be;

symbol: ["fa fa-fw fa-file, fa fa-fw fa-calendar"],
// Array(1)

Is this intentionally designed so? Or just an unexpected accident?

Thanks for the report (and sorry for the late replay). Can you pinpoint when this behaviour changed?
