            Bug ID: 186564
           Summary: list item marker vanishes when item content includes
                    certain MathML expressions
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: MathML
          Assignee: webkit-unassigned at lists.webkit.org

test case

Step to reproduce:
1. Load the attached test case in MiniBrowser

Expected results: The list item markers would be present for all three MathML expressions.

Actual results: The list item marker is missing for the 1st expression.

As you'll see when viewing the test case, changing the "∑" to "S" makes the bug not occur. That is the only change made between the 1st expression and the 2nd. Removing the "display='block'" also makes the bug not occur. That is the only change made between the 1st expression and the 3rd.
