Hi Damian, I apologize: I get so used to using groff from Git HEAD that I sometimes forget to check 1.22.4 behavior.
I also forgot about a bug fix I made over 2 years ago.

[eqn] Actually set "..." on text baseline.
* src/preproc/eqn/lex.cpp (troff_defs): Set the "..." token on the
baseline, not vertically centered, aligning the actual behavior with
what our eqn(1) man page has claimed since 2007.
Apparently botched in 62248e78a3433a07c417d988b85b79817069f5b5, 6
February 2007. (Actually in two ways, but one of them was
fixed in 55fe48afb48e1dca0f179bb710b161a1abb1c6ee, 5 January 2008.)
Fixes <https://savannah.gnu.org/bugs/index.php?59285>.
I would encourage you to write your eqn user's guide against 1.23.0.rc4.
I don't expect eqn's behavior to change at all between that RC and final
release, whenever that is.
Regards,
Branden
