It should?  Where was that done, and in response to what bug report or
discussion?

I see this in tooltip-show-help-non-mode:

      (let ((message-truncate-lines t) <<<<<<<<<<<<<<<<<<<
            (message-log-max nil))
        (message "%s" help)))

If I remove that binding, the echo area gets resized as expected to
show the full tooltip.  Should we remove that binding on the emacs-26
branch?
