Adding multiple multimedia assets changes iframe source url

Well I dived in it myself and found that each time you click "Add another item" it adds more entry's in the element array (in media.browser.inc at function 'media_attach_browser_js()' line 301). The variable browserUrl should be the same for each item so doesn't need to be added for each item seperatly.
The problem is in the function 'Drupal.media.popups.mediaBrowser.getDefaults' in media.popups.js (line 107) where it loads the browserUrl. If there is one item, the variable contains '/media/browser?render=media-popup' but more items turns it into an array and the variable outputs '/media/browser?render=media-popup,/media/browser?render=media-popup'.

My solution is not the best way but as far as I've tested it, it works. In media.popups.js, at the function 'Drupal.media.popups.mediaBrowser.getDefaults' (line 107) i've added an if statement to check wether it's an array or not. If so, only take the first entry of the array:

var browserUrl = Drupal.settings.media.browserUrl;
if (browserUrl.constructor.toString().indexOf("Array") != -1) {
	browserUrl = Drupal.settings.media.browserUrl[0];
} else {
	browserUrl = Drupal.settings.media.browserUrl;
}

And at line 121, I changed:

src: Drupal.settings.media.browserUrl; // Src of the media browser (if you want to totally override it)
into:
src: browserUrl, // Src of the media browser (if you want to totally override it)

As I said for now it works, but I'm not sure this is the best way to solve it.
Feedback/comments/improvements are welcome :)

yea, this is just a workaround, will keep an eye on the fat-trimming :)
