Do not search text in iframes with "display:none" style

[Title] Do not search text in iframes with "display:none" style
[Issue#] N_SE-47308
[Problem] Text search takes too long time in below site.
         http://m.soundcloud.com/tracks/search?q=webkit
[Cause] iframes with "display"none" have many strings but they are not visible.
[Solution] Do not search iframes which do not have renderstyle.
