Status: RESOLVED WORKSFORME

Horizontal scrollbar is not taken into account when calculating 100% body height. In the testcase if you shrink browser window so that horizontal scrollbar appears (below 600px), you'll also get a vertical scrollbar.

Reproducible: Always

Steps to Reproduce:
1. If windows is wider then 600px, there are no scrollbars - that's correct.
2. Now shrink (resize) browser's window to be narrower then 600px (blue part demonstrates it).
Actual Results:  
You get horizontal and vertical scrollbars.

Expected Results:  
You should only get horizontal scrollbar, because body height is set to 100%.

Body height should be calculated without horizontal scrollbar. It is not a part of a webpage. It works correctly with 100% width, but not with 100% height.

Almost certainly a regression from bug 240276, then.
