With floating windows, users have the desire to move editors out of the main window into the child window. Some of our editors use an absolute positioned iframe element that is resized and moved to fit into the editor area it belongs to. This will not work anymore as soon as the editor moves out of the window.

I already made a pass and configured currently unsupported editors with the new AuxWindowUnsupported capability.

This impacts custom editors as well as notebooks.

Steps to move an editor out to a floating window:

• remove the AuxWindowUnsupported capability for the editor of choice
• open such an editor
• trigger the "Move active editor into a new window" action from the command palette
