Brace layers and anchors

I’m using brace layer for a variable font Axes where only few glyphs change, and it is working nice except that anchors don’t seem to interpolate and the attached mark glyphs keep the position of the default master.

Is this expected? If yes, is there a work around or an alternative other than using full masters?

I just tried this. It seems that intermediate deltas for anchors are not supported, yet. Neither by brace nor by full layers. I’ll have a look.

Edit: I have to correct myself. With full masters, it seems to work.

@GeorgSeifert this issue is still there in Glyphs 3.1 !
will it be solved anytime soon?

We are planing some bigger changes for the variable GPOS export. This will solve the problem. Not sure if I can manage to get this done with the old code base.
