Reproducible: Always

The block containing "foo" is completely collapsed (but its border is visible,
and its content overflows).

This renders as expected with the old layout engine.

I just discovered and can confirm this bug report (was about to file it myself).
 I have a very simple layout which I'll attach which is my version of showing
the bug.  The layout should show a small box which is 90% purple, with a 10%
vertical strip on the right of blue.  In latest firefox, it is all blue (the
purple div, which is nested exactly as the original poster states, is an
absolutely positioned nested element of a containing div block which has
overflow hidden set, and the result is a zero width div in latest build).  It
works in Firefox 1.0.1 and ie 6, but not in yesterday's daily build:

Attachment: testcase renders incorrectly in latest build, ok in FF 1.0.1 and IE6

very simple test case should render a square 100x100 pixels, purple in left
90%, with a blue strip occupying the rightmost 10%, as a vertical strip.  in
latest ff, it renders entirely blue.
