System Information
Operating system: Linux-4.15.0-159-generic-x86_64-with-glibc2.27 64 Bits
Graphics card: GeForce GTX 1050/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 460.91.03

Blender Version
Broken: version: 3.0.0, branch: master, commit date: 2021-12-02 18:35, hash: f1cca30557
Worked: 2.93

Short description of error
Calling an operator from a button, with a modifier key, such as ALT, SHIFT or CTRL pressed is fairly common practice in the addon space.
The keypress event is simply checked for in the operator's invoke(), and consequentially a single operator can perform varying actions.

In 2.93, the same can be done when calling an operator via a gizmo.
In 3.0 however, the ALT key no longer works, while SHIFT and CTRL continue to work. This is even noticeable before the user clicks on a gizmo.
As soon as the ALT key is held down, the gizmo highlight disables, as if the mouse pointer wasn't located on top of it. This is true for native gizmos too, and again wasn't the case in 2.93.

Exact steps for others to reproduce the error

open the attached blend file in 2.93 and 3.0
run the script in the Text editor
- a gizmo appears at the cube's origin
- click it to call the ModkeyOperator and watch what it prints to the system console
  - hold down ALT, SHIFT, CTRLor nothing while doing this
in 2.93 it will print ALT in addition to the other possibilities
in 3.0 it won't print ALT, as it's never called with ÀLT pressed, instead the gizmo becomes inactive

Yeah, I can see the same pressing nothing/CTRL/ALT/SHIFT in this sequence

It's just doing nothing in 3.0 with Alt pressed. Well, and gizmo becomes inactive, yes.

This is because Alt is explicitly set to unchecked for gizmo_tweak:

If you enable Any, the "problem" is "solved".
This was intentionally changed in 83975965a7.
Therefore it is not considered a bug.
