CSS generated content (using :before or :after) does not resize dynamically. The
bug appears when part of the document needs larger space than initially loaded,
e.g. after loading a huge image without specifing the width and height.

I'm not sure if this is related to bug 215083.

Reproducible: Always

Steps to Reproduce:
1. Load a page with CSS generated content where the parent element would resize
after loading the (X)HTML.

Actual Results:  
The generated part remains the same in size.

Expected Results:  
The generated part should enlarge as its parent enlarges.

A workaround is to specify the width and height of the parent element.

Attachment: A simple test case

The upper part should look the same as the lower part.

I see the bug on the 1.7 branch and in 1.8a1, but not 1.8a6 or current trunk, so
it seems to be fixed on the trunk sometime after 1.7.
