Reproduction steps:
1. Create a new project
2. Click Edit > Shortcuts…
3. In the Shortcuts window, select “Scene View” category
4. Change shortcut for the “Pan 1” command to “Shift + Mouse 2”
5. Reassign the shortcut from “Focus” command, if prompted
6. Change shortcut for the “Orbit” command to “Mouse 2”
7. Close or minimize the Shortcuts Window and test the shortcuts in the Scene View

Expected results: Orbiting in the Scene View works with the Middle Mouse Button, and panning only when holding together the “Shift” key
Actual results: “Shortcut conflict” window pops up, saying “Mouse 2 conflicts with multiple commands”, while the multiple commands are “Pan 1” and “Orbit” which have different shortcuts
