Property Inspector shortcut keys don't take effect

### Tested versions

Reprodicible in:
- Godot v4.3.stable
- Godot v4.0.stable

This bug is **not** in
- Godot v3.4.4.stable.

### System information

Godot v4.3.stable - Windows 10.0.19044 - Vulkan (Forward+) - dedicated NVIDIA GeForce RTX 3060 (NVIDIA; 32.0.15.6081) - AMD Ryzen 9 5950X 16-Core Processor (32 Threads)

### Issue description

When assigning hotkeys/shortcut keys related to Property Editor (i.e. Inspector), they don't work, whether or not the Inspector is focused.

### Steps to reproduce

- Assign a shortcut to Property Editor > Expand All = Alt+X (Physical)
- Go back to Godot UI
- Click on Inspector to focus
- Press Alt-X

Result: properties not expanded
Expected result: shortcut should take the same effect as the Expand All function via the dropdown "tool" menu.

### Minimal reproduction project (MRP)

Bug is editor-related, not project-related.

Start by reproducing the issue in the Godot editor using the Inspector's Expand All shortcut and compare it with the Inspector tool menu action. Done means an assigned shortcut such as Alt+X expands the Inspector properties as the menu action does, on the affected Godot 4 versions.
