Popped-out window unexpectedly returns to main editor when toggling between visual and source modes

Summary

When using the editor, a popped-out window is returned to the main editor unexpectedly if the user toggles between visual and source modes. This behavior interrupts the workflow, as the window does not stay in the separate view as expected. It’s unclear if this behavior is intentional, but it may not align with user expectations for persistent, popped-out windows.

Steps to reproduce

1. Open a window within the main editor and pop it out to a separate window.
2. In the popped-out window, toggle between visual mode and source mode.

Expected results:

The popped-out window should remain in its separate state, allowing the user to toggle between modes without returning to the main editor.

Actual results:

The popped-out window returns to the main editor when toggling between visual and source modes, disrupting the user’s workspace.

Reproduce the issue by opening a window in the editor, popping it out, and toggling between visual and source modes. Trace the editor's popped-out window handling around that toggle; done means the separate window remains popped out throughout both mode changes.
