No, it isn't.  It's smashed.  Has no height.

The solution is not to use \smash when you don't mean it.  Otherwise it
will also cause collisions with text and other things.  There is not
anything sensible we can do: \smash is used in fractions and other stuff
for fixing vertical spacing, and we don't want to interfere there.
