Bug 112229

Summary:	REGRESSION (Subpixel Layout): "Popover" arrow shifts up at end of fade transition at hulu.com

Description Jon Lee 2013-03-13 00:01:48 PDT

1. Navigate to <http://www.hulu.com>
2. Hover over one of the items under “TRENDING NOW” to show a white “popover” with details

The popover fades in, then when it reaches maximum opacity, the triangular part pointing at the hovered item shifts up by a pixel or two.

It seems to depend on a calculation that divides by two. Depending on the thumbnail you hover (for example, further below in the page), you get either top: xxx.5 or top: xxx.0 (integer).
