If you right click a command, it will not actually get selected. This is especially annoying if you have previously selected a different command, as the context menu will show options for that command rather than the one you were hovering over when you right clicked.

1. Install Unity
2. Launch Unity
3. Create a new project with any settings
4. Go to Edit > Shortcuts...
5. Select any category
6. Select any command with the left mouse button
7. Hover over a different command and right click
8. When the context menu is open, hover over a different command and right click

Expected Result:
The command the mouse was hovering over becomes selected and context menu options are shown for that command.

Actual Result:
The context menu opens with options for the command selected in step 7.

Tested on Windows.
