QuickLook and PreFilter CP Bug

I found a little issue with the QuickLook of an OTF file. It shows a state of the paths/glyphs which doesn’t represent what the PreFilter in a Custom Parameter does with them on export time. If you open the OTF in Glyphs though, the drawings all look like expected, meaning the PreFilter was actually working properly. But the QuickLook state seems to be ignoring the PreFilter.

Also it would be super lovely if the PreFilter could be applied to the instance preview (in the Font Info > Instances). It doens’t.
