Steps to reproduce:
In the new RCs, saved window names seem to be suffixed erroneously by (1). This includes newly created saved windows. This only shows in the tab group selector - not in the Window menu or elsewhere.

Expected behavior:
Tab group listing for the saved window shouldn't have stray (1) in the title - should appear as it appears elsewhere.
