How to reproduce
- Create course with LTI element
- In LTI element configure to open in popup window
- Publish and run
=> Popup has no navigation element, no status and tool bar (depends on browser)
=> Pupup has no scrollbar, can not be resized (depends on browser)
Unfortunately as soon as one uses a specs element in the windows.open command, the default settings of the specs differs from the default specs when not using any specs at all. Thus, all specs must explicitly turned on to best match a normal browser window.
