refactor: reorganize transformInteriorValue

This code was checking a constantly true condition value !== CannotTransform,
that's why the code was not properly handling nested structure properly,
The code introduced by #8446 fixed this logic, by introducing another
duplicated piece of code.

This commit simplifies the logic here to reflect the original purpose.
