Oh, urgh. The problem here is our "full"/"googlefonts" builds. When we merge in the Latin subset, this subset also includes its own (but differently anchored) combining characters. I thought renaming the Georgian ones would fix it, but in retrospect it's obvious that they won't; the fact they lost cmap encoding is a second-order problem, but even fixing that won't help. More thought required.
