wt split-pane & wt new-tab commands open a new window

[ranyitz]

Environment

Windows build number: Microsoft Windows [Version 10.0.18362.657]
Windows Terminal version (if applicable): Version: 0.9.433.0

Steps to reproduce

For split-pane:
Run wt split-pane

For new-tab:
Run wt new-tab

Expected behavior

For split-pane:
Split the pane of the current window.

For new-tab:
Open a new tab in the current window.

Actual behavior

For split-pane:
Open a new window an split the pane in this window into two.

For new-tab:
Open a new window with a new tab in it.

Context

While this behavior is mentioned in the docs

Opens a new tab with the given customizations. On its first invocation, also opens a new window. Subsequent new-tab commands will all open new tabs in the same window.

It doesn't feel right to me. If those commands would not open a new window, we'll be able to get the same experience through command composition. (Open a new window and then split this one into two)

Now the behavior of programmatically splitting a pane or opening a tab in the current window (which feels like the broad use-case) is something that with the current implementation is not possible to do.
