Space added under icons with each added network type

I am wondering why I get space added under the icons with every new button added. In other words, if I have just facebook enabled, the spacing is perfect between the facebook login button and the branding below it.

If I add say Twitter as well, the spacing below increases and looks akward. if I add a third button, the spacing increases further and looks terrible. I tried looking int o the css and I see that the iframe height is being changed with “height: x !important;” which makes no sense because there is no reason the height should have to change considering the buttons are inline.

Please advise for a workaround for this problem…
