Support for Sparse Layers in Batch?

[jeremymickel]

I'm trying to generate a variable font from a designspace with multiple sources, including some UFOs with sparse layers. I'm not getting any error messages in DSE2, but I get this traceback when I try to generate from Batch:

fontTools.ufoLib.errors.UFOLibError: No such file or directory: '/Users/jeremymickel/Dropbox/MCKL/FONTS/FONTS/GoldwynSans/240205/Goldwyn-Black-support.redraw.ufo'

It seems to be looking for a UFO with the support.redraw name, instead of the layer within that UFO.
