System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce GTX 1070 with Max-Q Design/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 451.67

Blender Version
Broken: version: 2.93.0 Alpha, branch: master, commit date: 2021-03-23 18:34, hash: 3ea1779365
Worked: never

Short description of error
When you connect node properties to the Group Input sockets, the Float* properties are not exposed correctly. The properties show up under the modifier and are useable from the UI, however, none of them are usable from python.

Types that seem to work: NodeSocketInt, NodeSocketVector
Types that don't seem to work: NodeSocketFloatDistance at least

Exact steps for others to reproduce the error
geonode-python.blend

Load attached file
- Just an empty object using a Geometry node modifier which has a Cylinder mesh primitive with some of the properties connected to Group Input sockets (by hand; no python yet)
In the script editor window that's already open, execute bpy.context.active_object.modifiers["GeometryNodes"]["Input_5"] = 16
- This is the integer connected to the Vertices property
- The value will change once you mouse-over the properties panel, but the 3d view won't be refreshed until you refresh the object (e.g. toggle edit mode)
  - This is a quirk that could be addressed later, the real bug is below
Now try executing bpy.context.active_object.modifiers["GeometryNodes"]["Input_7"] = 4.5
- This is the element connected to the Radius property
- If you mouse-over the properties panel the input disappears(!) and the value does not take effect <-- The bug

Fascinating. I can confirm this issue.

I took a quick look but I think this is related to D9697: Refactor IDProperty UI data storage and #85306 (Use boolean in the modifier for exposed boolean node group inputs).
