    <thetext>Hi Team,

While looking into old Blink&apos;s commit, I came across another failing test case:

Test Case - https://jsfiddle.net/nqt0g1yz/

^ Does not show &apos;blue&apos; box in Safari / WebKit ToT while does show in Chrome Canary 126 and Firefox Nightly 127.

Blink Commit - https://chromium.googlesource.com/chromium/src.git/+/7afb0474da50c93fa2360fc70ccbb73a313a45f7

I did following changes and it compiles and progress following:

&gt; RenderTreeBuilder::move() 

if (normalizeAfterInsertion == NormalizeAfterInsertion::Yes &amp;&amp; is&lt;RenderBlock&gt;(from) &amp;&amp; child.isRenderBox())
        RenderBlock::removePercentHeightDescendantIfNeeded(downcast&lt;RenderBox&gt;(child));

and

&gt; RenderTreeBuilder::moveChildren() - Line 549

RenderBlock::removePercentHeightDescendantIfNeeded(*blockFlow);

and

RenderBlock::dirtyForLayoutFromPercentageHeightDescendants()

ASSERT(renderer-&gt;isDescendantOf(this));

___

Just raising so we can fix it.

Thanks!</thetext>
