Status: RESOLVED FIXED

(Core :: Layout: Block and Inline, defect)

Description

[Low Zhen Lin]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040414 Firefox/0.8
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040414 Firefox/0.8

Given a box
{
  float: left;
  overflow: auto; /* or scroll or hidden */
  min-width: 10em;
  padding: 1em;
  border: none;
  background: black;
}

Then, I expect a block of black 12em wide floated to the left.

However, I get a 10em wide black block floated to the left.

If I specify width: 10em instead of min-width: 10em, I get the expected results.

Reproducible: Always

Reproduced on Firefox 0.8/OS X (standard build)

Attachment: Testcase

A testcase. The green boxes have the correct dimensions, the red boxes don't.
