update bug explained in this answer looks fixed now. Problematic content mentioned below doesn't trigger user card popup anymore (tested with FF3.6 and IE7 / WinXP)
In Firefox 3.6 (Win XP and Win 7), my user card now looks like it's cut at bottom, as shown in red below. Note in IE 9 it looks OK. Also, the effect goes away after reloading the page in Firefox and returns back after Shift+Reload.
Could it be modified to show properly in Firefox without reload, as marked green - ie with dark-gray border at bottom?
I noticed this issue with About Me section content in my profile set to show combined SO flair:

Note the issue goes away when I add long enough summary to About Me. I plan to keep it as-is for a while just in case if needed to reproduce the problem. If needed, here's the link to one of my answers to look at it: link to example answer with my user card
