Steps to reproduce:
- In "Settings > Appearance > Show Tab" setting menu, choose "On the Side"
- Go to http://www.dummysoftware.com/popupdummy_testpage.html and click button "Safe New Window"
- The page opens a Pop-up window, this pop-up window is different from a normal window because it does not have a URL bar (location bar), but it still has the tab bar on the side (see screenshot)
Expected behavior: The pop-up window shows with no URL bar/location bar AND NO vertical tab bar / side bar
