Hello,
I use Opera 43.0.2442.806 with a start up option to 'continue browser where I left off'.
When I open new regular window of Opera, having a private-mode one already up, a clean session is started and further saved for next start up.

• This effectively makes me lose the tabs I left before.
• Is counterintuitive to the description - if I open first regular window, I expect it to work the same regardless of any other instances of the browser i.e. private-mode.
  Would that considered to be a bug or is it "a feature"?
  Cheers
