OK, that's interesting, you're using array assignment syntax ( vvar=( ... )
) but you're only assigning a single value; after that assignment, $vvar[1]
contains the entire contents of the file.  The blank lines aren't getting
lost here because they're inside that one string, rather than being their
own standalone values.

If you want to get the lines of the file into individual elements of an
array, you can use the (f) expansion flag to split the file contents on
newline. However, that will remove blank lines unless you also include the
(@) flag to preserve them.  Which gives the recipe I mentioned in my last
message:

    % vvar=("${(@f)"$(<testfile2)"}")
