Buttons on donation banner on about:tor are misaligned sometimes

Attached is a screen shot I took showing the donation banner with Laura Poitras and the new about:tor lookout for the alpha releases. There are at least two issues:

1. The buttons on the banner are not properly aligned.
2. While testing not only clicking on the buttons led to the donation page but this happened as well if I clicked somewhere on the banner and even if I clicked somewhere outside of it next to it. While I could live with the second case (although I think we should only go to the donation page if one clicks on the buttons) I am against the behavior in the third case: if one is not clicking on the buttons (banner) one does probably not want to donate and we should respect that. 2a) Probably related there is a little area on the left side next to the banner which seems to have focus as well.
