System Information
Operating system: Windows-10-10.0.17763-SP0 64 Bits
Graphics card: GeForce GTX 1080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 441.66

Blender Version
Broken: version: 2.82 (sub 6), branch: master, commit date: 2020-01-10 06:10, hash: 95200045f3

Short description of error
When using the "target_set_prop" to update the offset of the gizmo, we can see a tooltip on the screen when the pointer moves over the gizmo.
When using the "target_set_handler", there is no tooltip anymore.

Exact steps for others to reproduce the error
Using default scene and the factory setting,
In the preferences, check for the "Tooltips" checkbox.
Select the lamp and set the power to "1" to see the Gizmo.
Copy/Paste and execute the following script : There is no tooltip when the mouse moves over the gizmo.
Comment the lines 31 to 42 and uncomment the line 46, then execute the script again : There is a tooltip when the mouse moves over the gizmo.

Or use the following file :
handler_gizmo.blend

Thanks for your help.

- Example of a group that edits a single property
- using the predefined gizmo arrow.
#
- Usage: Select a light in the 3D view and drag the arrow at it's rear
- to change it's energy value.

I really don't know how this is implemented, but seems you should use both target_set_prop() and target_set_handler()

        ...
        mpr.use_draw_value = True
        mpr.target_set_prop("offset", ob.data, "energy")
        mpr.target_set_handler('offset', get=get_energy, set=set_energy)
        ...

I would suggest discussing issues like these in https://devtalk.blender.org
