[HarfBuzz] possible bug?

[Alfabety]

I have a Python macro to generate pngs.
hb-view is called from Python by:

...
features="--features='smcp=1,cswh=1,ss01=1'"
...
hbcall = (hb_view, margin, features, back, front, format, size, line, font, text)
...
hbout, hberr = subprocess.Popen(hbcall, stdout=subprocess.PIPE).communicate()

if I put some 'blind' feature at the beginning and end:
features="--features='xxxx=0, smcp=1,cswh=1,yyyy=0'"
both smcp and cwsh renders properly.
Without xxxx and yyyy doesn't work good
Better and deeper investigation next week.

best,

Ł
