Incorrect keyboard shortcut shown in menu.

• VSCode Version: 1.40.2 (also happens in 1.41.0-insider)
• OS Version: Pop!_OS 19.10 64-bit (which is very much like Ubuntu 19.10 Eoan Ermine)

Steps to Reproduce:

1. Press Ctrl+K, Ctrl+S to open the keyboard shortcut editor;
2. Find the entry for toggling the Activity Bar (workbench.action.toggleActivityBarVisibility)
3. Set its keybinding to "Ctrl + Super + A", which shouldn't be used by anything else by default; "Super" is the "Windows" key on PC keyboards, also known as the meta key in Linux.
4. Close the keyboard shortcut editor;
5. Open the "View" menu --> "Appearance"
6. See that the keyboard shortcut displayed next to "Show Activity Bar" is "Ctrl+A" instead of "Ctrl+Super+A"

Does this issue occur when all extensions are disabled?: Yes
