Splitting terminal opens default shell instead of current one

[wolf99]

• VSCode Version: 1.33.1
• OS Version: Microsoft Windows 10 1809

Steps to Reproduce:

1. Open a terminal with a non-default shell - e.g. my default shell in VSCode is cmd, so I would open WSL.
2. "Split" the terminal using the terminal menu bar icon, or the key shortcut (default is ctrl+)
3. The default shell, rather than the current shell.

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

Ideally the shell already in use in the terminal should be the one used for the split terminal.
On one level the current behaviour kind of makes sense, but is pretty unintuitive.
Also, with this issue in place, I'm actually not sure how else I can get a split terminal with non-default shell in any other than the first split?

Closing this out as designed, there are several ways to get the behavior you're after now with the commands and the new + dropdown in the panel. You can also pass args to the newWithProfile command:

Additionally there are complications if we allowed splitting the active terminal since it could have been created by an extension and not be a "real" terminal for example.
