The previous Popups test page pointed to the "Main page" which as
of Ie15487184a7f9fc08603fc42cfad3aeac6642dcc has specially handling
This makes a new test page "Popups test page 2" that is linked to from
"Popups test page" which previously linked to the Main page which
now leads to the display of a broken Popup
This gets our test fixed but the problem with main page previews
will remain (T215080)
