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.

This is the result of viewing the attached test case in MiniBrowser for WebKitGtk.
