https://wpt.fyi/results/mathml/relations/css-styling/writing-mode/force-horizontal-tb.html?label=experimental&amp;label=master&amp;aligned=

and only &apos;menclose&apos; failing here:

https://wpt.fyi/results/mathml/relations/css-styling/writing-mode/writing-mode-002.html?label=experimental&amp;label=master&amp;aligned=

___

*|* {
    writing-mode: horizontal-tb !important;
}

and remove from math {}.
