Neovim vscode plugin: cannot commit commands

Bug Description:

The neovim vscode plugin asvetliakov.vscode-neovim opens a textfield at the top of the editor (at the same location as the normal command field). However, in theia after entering the command/text the "enter" key is ignored. I didn't find another key that would work as workaround. In vscode it works as expected.

Steps to Reproduce:

1. Install asvetliakov.vscode-neovim vscode extension
2. In settings, set the path to the nvim executable
3. Restart theia
4. Open a file and type a command e.g. /some_search_string
5. Try to execute the command (enter doesn't work)

• Operating System: Linux (Firefox, Chromium)
• Theia Version: v1.2.0 via Gitpod
