Why does the size of a div element change when changing position from fixed to absolute?

ThiefMaster

I have a div containing some text. This div used to be position:fixed, but for some reasons I need it to be position:absolute.

However, when changing it from fixed to static its size changed (the “auto-sizing” during fixed display was nice and should be preserved).

Here’s a minimal example: http://jsfiddle.net/ThiefMaster/yBRa9/3/

I’m looking for a way to keep position:absolute without the element shrinking to the lowest possible size.

Using JavaScript it’s easy to achieve but if it could be done without additional JS it would be nice.
