57906 - :root element grows to fit contents [BG] (stretches)

Status: RESOLVED FIXED

(Core :: Layout, defect)

Description

[Hixie (not reading bugmail)]

When the HTML has content that extends outside of its content area the HTML
element's frame is getting sized as wide as the content. This should not 
happen. The content that overflows should be subject to the 'overflow' policy 
of the parent element.

STEPS TO REPRODUCE:
   View the attachements.

EXPECTED RESULTS:
   The outer blue border (the HTML element) should be the width of the viewport.

ACTUAL RESULTS:
   The outer blue border goes off theright hand side of the window.

That's not how it should work in CSS. Because the HMTL's width is specified as 
'auto' it is computed based on the viewport width, and that is the final value. 
Regardless of whether content overflows.

This broke out of bug 35681.

Is this the same problem as described in Bug 36338 (text wraps beyond window if 
HR width is larger than window)? Just want to make sure because it was marked a 
duplicate of Bug 35681 (the originator of this one) and it's still not fixed. If 
it is the same, the very simple test case there may be helpful.
