`<C-j>`/`<C-k>` don't work in command edit box

Describe the bug

If you go to the command edit box that opens at the top of VS Code, ctrl+j/k don't work to navigate options. They work in autocompletion box.

The command edit box is opened when you go to symbol (ctrl+shift+o), look for file (ctrl+p) and run command (ctrl+shift+p).

To Reproduce
Steps to reproduce the behavior:

1. Open file with methods eg JavaScript file.
2. Press ctrl+shift+o to go to command box at top to view symbols
3. As you start typing, the list of symbols appears.
4. Press ctrl+j or ctrl+k to navigate up and down list. Nothing happens.

By default ctrl+j toggles a pane. I disabled this mapping.

Expected behavior
I expect the highlighted symbol (or file or command) to change. When I press Enter I expect the highlighted symbol to be selected.

Environment (please complete the following information):

• Extension Name: vim
• Extension Version: 0.17.0
• OS Version: Windows_NT x64 10.0.17763
• VSCode version: 1.30.0

Additional context
Add any other context about the problem here.

Reproduce the issue from the listed VS Code shortcuts: Ctrl+Shift+O, Ctrl+P, and Ctrl+Shift+P, then inspect how the command edit box handles Ctrl+J and Ctrl+K compared with the autocompletion box. Done means these keys move the highlighted symbol, file, or command and Enter selects it.
