fix chrome extension.

- i've an extension which has a padding/position issue, see video capture [login to view URL] - i tell you about the issue: most extensions have a dialog set in [login to view URL], so chrome know where to place put the dialog. the issue here is that in this extension on the manifest it's defined like [login to view URL] so chrome can't know the position, this is the issue to fix - link to download the extension [login to view URL]
