Keyboard layout action of "type": "string" do not work (e.g. CMD layout)

Have put together a layout for Vim and wanted to enhance using ideas from https://swordfishslabs.wordpress.com/2015/02/27/json-profiles-in-ubuntu-terminal-app/. Relevant section:

{
    "main_action" : {
        "type" : "string",
        "text" : ":q",
        "string" : ":q\n"
    },
    "other_actions" : [
        {
            "type" : "string",
            "text" : ":wq",
            "string" : ":wq\n"
        },
        {
            "type" : "string",
            "text" : ":q!",
            "string" : ":q!\n"
        }
    ]
}

Tried this but it didn't work. While checking the other layouts, noticed that the CMD layout relies on string as well and then found that none of those work either. Asked a question on the Telegram group and confirmed that this wasn't working for others, either -- viz. @Fuseteam & @advocatux.

@wagafo Can this be labelled as a bug instead of an enhancement? Since this is functionality that is already in the app that isn't working. Meaning, the CMD layout which is provided by default.
