Please describe the problem:
Double cursor is appearing when try to delete some specific conjuncts (GSUB)
with backspace. Not applicable for all conjuncts. But Its not appearing if those
specific conjuncts places alone ---- Not within any word. Creating problem only
when those appearing within any word and followed by dependent vowels like Vowel
sign AA (U+0B3E)(inscript 'e') and followed by any other GPOS. This is the
observation result so far.
