When you close the last tab of a window, it is not possible to close that window. The URL of the last closed window will "shadow" appear in the URL entry space. Maybe if I open a new tab then it is possible to close the windoow, but that clearly is NOT how things should work. MacOs Sonoma 14.2.1. Orion Version 0.99.126.4.1-beta (WebKit 618.1.2)
Doh! I expect the window to close.
