Default action for opera.exe does not work well for Many Desktops in Windows 10

(TL;DR below)
Situation: I have two desktops opened in Windows 10. In the first I open Opera which is attached to my task bar.
Now if I right-click on the icon in the taskbar I can either specify whether I want to open a new tab or a new window or I can just launch the application generically.
Here comes the interesting part. Opera-people decided that the default action is to always open a new tab if there is any opera window already opened. This was fine and whether you like it was a matter of taste. Up until Windows 10 was released.

What changed? Windows 10 got the ability to manage several separate desktops.

([TL;DR]-People start here) With Windows 10 on a second desktop, if I start the opera application and there is already a window opened on the first, it switches back to the first desktop and opens a new tab in that opera window.

As someone who wants to use Opera for all things internet and always, but wants to separate different workflows cleanly, this is annoying.

Reqested Solution:

• Either keep it the old way and make opera take multi desktops into consideration ...
  or
• Let people choose in settings->browser to make the default action for the executable always open a new window.
