Behdad Esfahbod ec925ece05 [khmer] Reinstate a pause after basic features 
This was removed as part of 044d7a06db,
which caused the regression.  Just adding a pause fixes the shaping.
Debugged by just tracing the good/bad shaping and observing the
lookup orders intermingling in the bad shaping.

Test:
hb-shape LeelawUI.ttf --unicodes U+1780,U+17D2,U+179A,U+17BB
