Media Upload Thickbox Styles Broken After 3.9.1 Upgrade

[erayalakese]

Hello,

I'm adding a new metabox , with ​this functions. It's adding a new metabox which contains a link. And when user click to link , WP's default media uploader thickbox screen appears. It was working great at WP 3.9 version. But its styles broken after 3.9.1 upgrade.

You can see this error with fresh WordPress installation. Just follow this steps :

1) Install WP
2) Add at least 5-6 images to your media library.
3) Add ​this codes to your functions.php file .
4) Browse to wp-admin > Add New Page screen.
5) Click Alt Başlık Görseli Ayarla link on Sayfa Alt Başlığı metabox.
6) Go to Media Library tab.

It was working great at 3.9 . But now there is a problem with Search Media textbox and button's position.

Thank you.

Patch for ticket #28220 . media-upload.js and media-upload.min.js files updated.

I wonder if we can just disable MP6-styling in the old media modal (cc @melchoyce, @helen?). I don't think the proposed solution here is wide-reaching enough (changing the default width of the old media modal to sidestep the media query that breaks the styling here).

In 28830:

The "old iframe media modal" has some pretty busted styles. Although this is a "deprecated" feature, clean up some of the broken styles.

Props erayalakese for the JS patch.
Fixes #28220.
