It seems like it should be, but it's not working for me as I expect. I don't think I have a syntax error, so I'm not sure if I'm missing something, or if this just really isn't possible with Glyph Construction.

Base Glyph dotlessi

Accent 1, dotaccentcomb

Accent 2, ogonekcomb

Unexpected result #1

idotbelow=dotlessi+ ogonekcomb@ogonek + dotaccentcomb@top

Reversing the order of my glyph recipe comes closer, but still isn't what I'm hoping for:

idotbelow=dotlessi+dotaccentcomb@top + ogonekcomb@ogonek

Have I made some kind of simple error, here? The only hack a collaborator could find was to put a _top anchor in the /ogonek, but that seems like a really overly-complex workaround which could come back to bite me later.

idotbelow = dotlessi + ogonekcomb@ogonek + dotaccentcomb@dotlessi:top
