The first item in the fixed-overflow panel has too much margin-top. We should only be setting margin-top for items that are not the first-child. This rule here is the cause of the problem, http://searchfox.org/mozilla-central/rev/5bb6dfcb3355a912c20383578bc435c1d4ecf575/browser/themes/shared/customizableui/panelUI.inc.css#1382 It is currently matching on the first selector, `panelview .toolbarbutton-1`.

Eh, meant to comment here when duping, but for completeness' sake: I duped this because ultimately, for the photon styling we want to get rid of the margin completely, and so updating the selector only to exclude the top item isn't really that useful, and it seems to me verifying the new styling will also verify this bug, so keeping a separate bug open doesn't seem worth it.
