Opera Bug?

View screen shots via BrowserCam. Another page with three examples (including IE support) is also available.

Above is a paragraph with eight links. The paragraph is styled as display: table and each link is floated left and given a minimum width of 16px. The minimum width is used to accomodate an untiled background image. (Images removed to help minimize the test case.)

Forgetting Internet Explorer for the moment, Firefox and Safari display one row of eight links, each one 16px wide - exactly what I would expect.

Opera 8.5 and Opera 9 display two rows of four links each within a 64 pix wide block (not counting the border). By changing the minimum width, notice that Opera will maintain the 64 pix width, shifting the numbers around as needed.

Ideas on how to fix? Is it a bug? A feature? A momentary lapse? None of the above? Please let me know!

UPDATE (1 August 2006 15:55 EDT): See three more examples. The third example is the closest I've come to resolving this yet!

Kind of problem

Spec Violation, Web Page

Summary

Double-centered, floated blocks break across two lines

Steps to reproduce

Markup a paragraph with eight links, one character (CDATA) each.
Style the paragraph as display: table and center it via margin: 0 auto.
Float and center text-align each link.
Give each link a minimum width of 16px. (I need this to tile a background image but note that images are not needed for this minimal test case, just a min-width.)
To aid in seeing the result, add a simple border around the paragraph and a background color to each link.

Expected behavior

I expect to see a single row of eight numbers, each one with a minimum width of 16px, as seen in Firefox 1.5 or Safari 2.0. (To see this in Internet Explorer 6 or 7, I also have a non-minimal test case linked from the example above, but thought you'd do better with a minimal test case for starters.)

Actual behavior

I see two rows of four numbers each. The expected single row seems to have wrapped! Furthermore, if the min-width is increased or decreased, the overall width of the paragraph is maintained. If you look at the non-minimal test case at http://test.joesapt.net/cf/opera this adds IE 6/7 support. The markup is a bit more involved, but notice that Opera 8.5 now shows the expected result! Opera 9.0 still shows two rows. (Windows/MacOS - doesn't matter.)
