[Bug 24015] New: League of Legends initial dialog doesn't show all content and doesn't let you play

http://bugs.winehq.org/show_bug.cgi?id=24015

Summary: League of Legends initial dialog doesn't show all
                    content and doesn't let you play
           Product: Wine
           Version: 1.3.0
          Platform: x86
               URL: http://leagueoflegends.com
        OS/Version: Linux
            Status: NEW
          Keywords: download
          Severity: normal
          Priority: P2
         Component: mshtml
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

The initial window that comes up is nonfunctional; content doesn't show, and
you can't proceed to the game.  'winetricks ie6' works around this.

To reproduce at the moment, follow the appdb's howto, i.e.
patch wine to get around bug 20296 and bug 21870, and do a full install from
e.g.
http://www.fileplanet.com/204655/200000/fileinfo/League-of-Legends-Client-%2...
to get past bug 22152.
Then do
  cd ~/.wine/drive_c/"Riot Games/League of Legends"
  wine lol.launcher.exe
and let it update overnight.  When it's ready, you should see some news
items, and clicking on Play should do something.

Doing 'winetricks ie6' works around it; marking mshtml.dll as wine-only
recreates the problem, and when you click on Play, you see log entries like
