offset() return wrong top in Firefox 4.0.1 if using font-size:13px/1.231

[[email protected]…]

Using offset to recover the left and top position of an element with a body with this size of font:

body {

font:13px/1.231 arial,helvetica,clean,sans-serif; /* for IE6/7 */ *font-size:small; /* for IE Quirks Mode */ *font:x-small;

}

give like +9 pixels of top position. Check this image for better understanding:

Im using Yahoo Reset.css version: 2.8.2r1, thats why the strange font size.

If i change from 13 to 11, then the top position with offset (and position() ) becomes ok. Im using Firefox 4.0.1 an other browsers (didnt test in IE) works ok.

The problem I see with patching Firefox 4 bugs now is that Firefox is moving to an auto-update model similar to Chrome. In August of this year, the current version of Firefox will be 5 and 6 will be on the way.

Ok, heres the demo: ​http://www.xhelos.com/game/colony.php?colony_id=260

Just open a Firebug console and execute this:

renderConstruction($('#Row12 #Column0'),xenoconstructions?[479])

Make sure to change the size of the body as the first image to note the difference.
