15326826bf [aat] Ignore cross-stream offset of deleted-glyphs 
I think it makes sense to accumulate it, but Ned tells me that's
what CoreText does.

385f78b312 [aat] Remove deleted-glyhs after applying kerx/kern 
Finally:  Fixes https://github.com/harfbuzz/harfbuzz/issues/1356

Test case:
$ ./hb-shape GeezaPro.ttc -u U+0628,U+064A,U+064E,U+0651,U+0629
[u0629.final.tehMarbuta=4+713|u064e_u0651.shaddaFatha=1@0,-200+0|u064a.medial.yeh=1+656|u0628.initial.beh=0+656]

The mark positioning (kern table CrossStream kerning) only works if deleted
glyph (as result of ligation) is still in stream and pushed through the
state machine.
