I opened a PDF file sometime back and cannot permanently delete the tab. I close it by clicking on the X in the tab and it closes. The next time I open Brave, the tab appears again and i have to again close the tab. If I right click on the tab and choose close, Brave closes completely. If I try right clicking and use detach, nothing happens. If I try to Pin and then unpin, the tab reopens when I re-open Brave.Any help to remove this tab will be appreciated.
