And that initialization works for you without having to resort to the
'user-position' parameter?

I couldn't tell.  If you run Emacs 25 and 26 in parallel on the same
system you could try to debug the parts where the WM hints are
processed and look whether these versions do anything differently.
Otherwise, you would have to bisect your Emacs to find out.
