User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20170419042421

Steps to reproduce:

Open a moz-extension: page with windows.create() and type "detached_panel".


Actual results:

It shows a blank page, but the content is loaded. When right clicking to open a context menu, the content appears normally.


Expected results:

It should show the page normally from the start, as with Firefox 52.

Type "popup" and "panel" do the same as "detached_panel"; type "normal" shows correctly.
Loading an http: page works as expected.
