Created attachment 342540 [details] 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.
