Can't answer that, my Babylock coverstitch does definitely
unravel if you pull on the looper stitch. I think it's the
nature of the beast, the stitch is formed using a chain
stitch. My instructions say to give the needle stitches a
firm yank, then thread them into a sewing needle and poke
them to the back side, where they are tied off to the looper
thread. That works so far for me, but would not be a
solution if your problem is caused by *broken threads* in
the line of stitching.

Have you tried something stretchy, like wooly nylon, in the
looper? And maybe even in the needles? Do you have
differential feed? If so, you could test breaking point
using different threads and differential-feed settings to
see if some combination would work better for your
application.

I think maybe you are comparing apples to oranges. My
Huskylock 936 can be converted to do a coverstitch. I
haven't tested it, but I doubt it forms the stitch
differently than the Babylock CS. On the other hand, there
are coverstitch machines which form the loops on both the
top and the bottom, perhaps they are less likely to come
undone(?), but I don't know if they are available for the
home-sewing market.
