Following Source Browser in new Window

edit

If I open a separate window by moving a tab outside his former IDE parent, this new window seems to be no longer connected to 'Source Browser' navigation (and probably other centralized tools). Instead, the file will be re-opened in the parent of the Source Browsers pane again, when double-clicking an element inside the browser.

I attached a single-monitor example for the constellation (the new adapter.py tab not yet opened on the left side). I would like this, because I'm using this variant often in multi-monitor setups. But the second window seems to be an almost independent incarnation with respect to this and similar cases. In my opinion, it is more decoupled from the whole application than desirable.
