System Information
Operating system: Linux-5.15.5-76051505-generic-x86_64-with-glibc2.31 64 Bits
Graphics card: NVIDIA GeForce RTX 3080/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 470.86

Blender Version
Broken: version: 3.0.0, branch: master, commit date: 2021-12-02 18:35, hash: f1cca30557
Worked: (newest version of Blender that worked as expected)

Short description of error

Holding ALT to change multiple objects's same attributes of modifiers is a commom practice, but it doesn't work when the attribute is part of a Geometry Nodes Modifier.

Exact steps for others to reproduce the error
alt-hold-not-work-gn.mp4

Duplicated you object with an arbitrary attribute exposed to the Geometry Nodes Modifier.
With both objects selected, hold ALT and change the value of the exposed attribute.

Conclusion:
The expected behavior would be that both objects would get the same values updated but only the active object will.
This works for the other modifiers and in many more areas of Blender. Is it a limitation issue or a lack of consistency (to-do)?

Can confirm, will check...

This is because internally geometry nodes modifier's properties are stored as ID properties it seems.
And for these (also e.g. python defined ones like https://docs.blender.org/api/master/bpy.props.html), this seems to fail generally...

Apparently this does seem to work on ID properties [not sure how that went wrong the first time testing... or I am having an extremly bad day in regards to testing...]

Now this gets embarrassing, will have to backflip again it seems...
