No, that's not correct at all.

Fixing it the right way will be very invasive, and risks breaking the
xls (not xlsx, xls the binary) import and export filters into utterly
useless state (I mean, really useless).  This is because so much code is
shared between the xls import/export filters and the xlsx export filter,
and the offending code is in the common part of the filters code, and
its effect is broad.

So, the fix has to be followed by intensive and comprehensive testing of
the xls import/export filters to make sure they work just as correctly
as they did before the fix.  Unfortunately it was much more
time-consuming than we had hoped & we didn't have enough time and
resources to pull that off for 3.3.  But we need to fix that sooner
rather than later, and I'm hoping that we will finally nail it in 3.4.
