Short description of error
Mantaflow doesn't notice when geometry nodes are used to modify a mesh. Looks like it could be related to if the object is keyframed or not.
Exact steps for others to reproduce the error
Open the attached file and in the Fluid Domain click Bake All.
Run the animation.
The inflow follows Cube1 but not Cube2. The difference between the cubes is that Cube1 has a keyframe on location, but it seems like it doesn't matter which property is keyframed.

Changed status from 'Needs Triage' to: 'Confirmed'
The thing is that this seems broken even for shapekey animation etc., quite bad...
shapekey.blend
I have checked other modifiers incl. Armatures and Lattices, these still seem to function correctly.
Will report this separately
The shapekey issue is in #88566 (Mantaflow inflow with shapekeys is not working anymore (regression))
