Steps to reproduce

I'm attempting to open a new tab and then send input in that new tab using the multipleActions command.

{
    "command": 
    {
        "action": "multipleActions",
        "actions": [
            {
                "action": "newTab"
            },
            {
                "action": "sendInput",
                "input": "\u001b[A"
            }
        ]
    },
    "name": "Send Input Test"
},

Expected Behavior

The new tab should have the input sent from sendInput, which in this case is as if I pressed the up arrow in my buffer.

Actual Behavior

sendInput seems to be completely ignored and my input line is empty.

Huh. Good point. I suspect that we just fire-and-forget these guys after startup. Kinda interesting that the input doesn't go anywhere though - not into the previous tab or the new one. That's odd for real.

So sendInput is only a problem if it's called after a new terminal control is created. If you just do two sendInput actions one after another they work fine.

The problem with running sendInput after newTab or splitPane is that the ConptyConnection hasn't been started yet - the ConptyConnection::WriteInput() method does nothing if the connection hasn't started.

I guess you could make WriteInput() store the strings that are sent to it if it's in the NotConnected state, and re-play them once it gets into the Connected state?

It's not working for me:

{
    "name": "blah",
    "command": {
        "action": "multipleActions",
        "actions": [
            {
                "action": "sendInput",
                "input": "sensible-browser https://...\n"
            },
            {
                "action": "sendInput",
                "input": "sensible-browser https://...\n"
            }
        ]
    }
}

That just launches the first URL for me...

Running it in WSL/Ubuntu Profile.

Any known workaround for this bug? Sending the input twice is not working for me
