U+1824 & U+1826

Hi Greg,
I just checked http://r12a.github.io/scripts/mongolian/variants again
and found an issue at U+1824/1826.
If we should filter FVS-s strictly, then we should probably consider u &
ue with drop which occurs after NA alternatively.
@Siqin & Jirumutu: Is this form exists in Inner Mongolia? If yes, how
popular is it?
