These tests compare scripted elements (e.g. `munderover` or `mmultiscripts`) with empty scripts (e.g. `<mspace/>` or `<none/>`) against the equivalent constructs without the empty scripts (e.g. `mover`, `msup` etc). Gecko has some specific adjustments to make them render the same, taking into account "ink" and logical metrics. It's not clear whether this is aligned with MathML Core and one of the test is even failing on some platforms (likely due to different system fonts) so for now we just keep them as internal WPT tests.
