Fix Misaligned Facebook Share Icon

I had the following situation happen:

Misaligned Facebook Share Icon

Misaligned Facebook Share Icon

I took a closer look when Chrome debug tools and found that Facebook was including an element with a vertical-alignment of bottom. This turned out to be the culprit and it is easily fixed with a basic CSS override.

div.fb_iframe_widget > span {
    vertical-align: unset !important;
}

All this does is unset whatever custom value was set for vertical-align.
