I always use my Opera with my WhatsApp pinned on the left side. Often I want to drag one of the tabs to another screen to use that website there, but when I do this, the WhatsApp also opens pinned in that window, stealing the log in, and logging it off at the other instance of Opera.

This does not make sense, when I drag a tab to a different screen to open it in a new window, WhatsApp should stay where it is.

Is it possible to change this behaviour?
