If there is a spelling error in conditional text, it is not spell checked.  

Example: Field gender has the value female

Function conditional text 
gender EQ "male"
then Abcdefghijklm
else Nopqrstuvwxyz

Document shows Nopqrstuvwxyz as a field as well as Nopqrstuvwxyz outside of the
field (because I also typed it outside of the field)

Actual result: Nopqrstuvwxyz has a wavy red underscore only where I typed it
outside of the conditional text.
Expected result: Nopqrstuvwxyz has a wavy read underscore both where it appears
in the conditional text as well as where it appears directly typed outside of
the conditional text.
