Hi Luboš,

I think this issue is related t0 how pre-coumputed glyph items are handled for
fallback layouts, which was introduced in 7439cabc643d. 

OutputDevice::ImplGlyphFallbackLayout does not generate level>1 fallback
because those fallback glyph items have been removed. But even if I try to
force it to use pre-computed glyph items, the layout still messes up. I guess
it's because the glyph item cache are not valid, after adjustment.

Do you have insight about how can this fixed?
