SVN commit 587726 by ggarand:
Remove incorrect special casing of root block.
Webcore needs this hack because it still uses the old root-is-initial-containing-block model,
but we don't, so there is no need to break the spec here.

Version: (using KDE KDE 3.5.4) Installed from: FreeBSD Ports Compiler: gcc 3.4.6 OS: FreeBSD if the root element is relatively positioned, then for sufficiently high body child that overflows the viewport, the absolutely positioned descendant with the root as containing block will be mispositioned. For bottom: 0 offset, it will be offset against the initial containing block, the viewport, and not its nearest positioned ancestor, in thsi case the root element. This is a spec violation in KHTML 3.5.4. Testcase below. <!DOCTYPE html> <html> <head> <title>position: relative on root and bottom: 0 on positioned descendants</title> <style type="text/css"> html { position: relative; } body { height: 2500px; } h1 { position: absolute; bottom: 0; } </style> </head> <body> <h1>FAIL</h1> <p>You should not be able to see the word FAIL without having to scroll.</p> </body> </html>
