We created a test case that executes the not-yet-tested code block at https://searchfox.org/mozilla-central/source/layout/generic/MathMLTextRunFactory.cpp#639.
However, the test is missing a functional check (is(..) or ok(..)) to check that the behavior of the code block is correct.

Please complete the test and add it to the test suite, if you think it is worth to do so.

In the attachments we provide the generated test (test.html).
It reaches the targeted code block through the stacktrace in stacktrace.txt.
We also provide some additional generated tests that target the same location (alternative_test_N.html).
