    <thetext>According to the spec [1]:

&gt; The float property does not create floating of elements whose parent&apos;s computed display value is block math or inline math, and does not take them out-of-flow.

    <thetext>Alternative, maybe we can temporarily do that &quot;if the parent is a MathML element&quot; but not sure how easy it will be.

Also for grid/flex we force computed value of float to none for flex and grid displays in the style adjuster, maybe we can temporarily do that for MathML too:  https://github.com/WebKit/WebKit/pull/31676#discussion_r1741769280</thetext>
