If a FeatureVariationRecord with the same ConditionTable exists re-use
it and append FeatureTableSubstitutionRecord’s.
Without this, in the following feature code only the first lookup will
be applied since there will be two FeatureVariationRecord with the same
ConditionTable, so the first will be matched and the other will be
skipped:
conditionset test {
wght 600 1000;
wdth 150 200;
} test;
variation ccmp test {
sub e by a;
} ccmp;
variation rlig test {
sub b by c;
} rlig;
With this change only one FeatureVariationRecord will be created with
two FeatureTableSubstitutionRecord’s.
