Steps to reproduce

Open a Terminal Preview instance with v1.23.10353.0.
Create a new tab from an existing profile.
Duplicate this into 2 new tabs (Which should inherit tab name font size etc).
Duplicate a new pane (Split) inside the last created tab.
Apply a colour to the tabs.
Drag the last tab (With the split pane) out of the main window to become its own window.

Expected Behavior

The tab should maintain the pane, color and font settings when becoming a window.

Actual Behavior

When converting this tab to a window it loses the pane, also sometimes loses the tab colour and font size setting.

This does not occur with Terminal v1.21.10351.0 which behaves as expected.
