Caused by e968b4197b / 67e23b4b29

Short description of error
If you us a smoke domain to guid a liquid you get no result because there is an error in the console that shows that two variables are undefined.

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "<string>", line 250, in bake_guiding_166
  File "<string>", line 235, in bake_guiding_process_166
NameError: name 'x_guidevel_s166' is not defined

  File "<string>", line 334, in fluid_pre_step_166
NameError: name 'weightGuide_s166' is not defined

Exact steps for others to reproduce the error

  1. Open the file.
  2. Configure the cache folders in both domains.
  3. Bake the smoke domain.
  4. Bake the liquid domain (you will see the error in the console and no liquid in the scene).

It looks like this was caused by 05952aa94d
(there is a bit of uncertainty to this though since with that commit, I dont get mentioned error in the console, bake is broken nonetheless with that commit)

OK, so we have another regression (from 3.6 > 4.0)

Now overlapping domains (as in this file) will cause the smoke to not display in the viewport... :/

Will check when that happened

Reported this separately, see #116985

Scratch that (dont know why I came to that conclusion...) It is actually caused by e968b4197b / 67e23b4b29. Solution is a bit tricky (I have a fix already for this scenario, but breaks elsewhere), needs some further investigation

Puh, took me a while to figure that one out, but a patch fixing this should be in !117067
