Jay has given you the only 2 options I know of.
FYI, the reason is that in Word 2013 MS changed the "Drawing Engine", the part of the program that is used to "draw" the document on the screen. From the comments I've seen from MS, this is the way it was always "supposed" to work. In other words, what
we got used to previously was the result of "broken" code. The code was "fixed" to show what we see now, and MS says there is nothing left to "fix", they currently have no intention of returning to the old display approach.
This article describes the "benefits" of the new drawing engine: http://blogs.office.com/2012/08/21/updating-layout-in-word-2013-while-maintaining-compatibility/
I also have this "note" in my working notes:

NOTE 2013:
Unfortunately, as you have discovered, text boundaries in Word 2013 are useless. This is due to the new layout engine used in Word 2013. It turns out that Word's developers had no idea that so many users depended on text boundaries, which we have
been told were kind of a mistake to begin with, "a feature that was never supposed to be a feature," "a window into the internals of word" that should probably never have been exposed to users.
The feature "just draws a border around [Word's] internal drawing rectangles," and those have now changed with the switch to a hardware-accelerated display. So Word "is doing precisely what it has always done (drawing borders around internal data structures).
Unfortunately, this means that scenarios that used to work accidentally now don’t work the same way. There’s really no way to bring back the old functionality – it truly doesn’t exist."
