Worker seems to be processing [Embed] tags

[miki-shalala]

im using some fonts im Embedding via [Embed] tags
[ im embedding fonts as a symbol from another SWF ]

the worker way of doing it would be to use:
Worker.current.isPrimordial
but so far it seems it wont work ( im scouting the app and it is allocating memory on parseTag method )
so, how do i prevent fonts from embedding on the worker thread?
or:
how do i check if the code is running on the worker or the thread?
thanks.

EDIT: i worked around it by loading the fonts using a Loader
