Status: RESOLVED DUPLICATE of bug 1171419

(Core :: Layout, defect)

Description

[Mike Cardwell]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:35.0) Gecko/20100101 Firefox/35.0
Build ID: 20150122214805

Steps to reproduce:

Given this html:

<ol>
    <li>Item1</li>
    <li>Item2</li>
</ol>

As soon as you add a flexbox display to the <ol/> using CSS, both <li/>'s start "0." instead of "1." and "2."

Attachment: testcase 1

I can reproduce. Here's a testcase based on comment 0.

(Mike -- thanks for filing the bug! Just a heads-up, for future bugs: instead of pasting your test-HTML into a comment, it's best if you can use Bugzilla's "add attachment" functionality to attach a simple testcase that demonstrates the issue.  That way, Mozilla developers / bug-triagers can instantly see what you're talking about, just by loading your attachment, and they can be sure they're actually testing the same thing that you are.  In this case it was pretty easy for me to make a testcase, but sometimes when we paste HTML from a bug-report comment into a local file, it doesn't look anything like what the bugreporter described, because it turns out other styles & markup are required.)

dbaron says this is likely a version of bug 4522 --> marking as a duplicate of that bug.
