Research direction
Start with the linked Monaco Editor Playground example and reproduce the issue through monaco.editor.create using a very long single line with plaintext and automaticLayout enabled. Test clicking "show more" at the end with word wrap disabled. Done means the available string is displayed without the desktop editor closing or the browser page becoming unresponsive.
