When I try to use the Chrome Developer Tools, it seems I can no longer view it in a new window.
Is this a bug or was that really an intended change in an update?
If you need to open the DevTools press ctrl-shift-i.
If the DevTools window is already opened you can use the ctrl-shift-d shortcut; it switches the window into a detached mode.
For example in my case the electron application window (Chrome) is really small.
It's not possible to use any other suggestions except the ctrl-shift-d shortcut
