It turns out that a possible workaround is making sure that the markup 
has top coordinate zero. Try this:

#(define-markup-command (show-extent layout props arg) (markup?)
    (let ((stil (interpret-markup layout props arg)))
      (ly:message "X: ~a\nY: ~a\n\n"
                  (ly:stencil-extent stil X)
                  (ly:stencil-extent stil Y))
      stil))

\markup
\show-extent
\general-align #Y #UP
{ \box \line { \vspace #3 text } }

(The show-extent command is only for displaying the stencil extent of a 
markup; the actual change is in calling \general-align.)

I still don't understand the mechanics involved, and of course it's not 
desirable for you to have to put all of your markups in a \general-align 
command. (Even though this could probably be automated by manipulating 
the top level markup handlers.)
