In Cockpit, the stacktrace window allows for horizontal resize which can be pulled outside the parent container

With CAM-10400 we introduced an embedded stacktrace window in Cockpit for failed jobs.
This window includes a resizable text area that can be stretched in both dimensions.
This might end up like this:

It should suffice to have this text area being resizable vertically, since users still can open the stacktrace in a separate tab or copy the trace easily if the window is not wide enough.
