REGRESSION(264248@main): A floating element can cause a list item's bullet to
be orphaned on overconstrained lines
https://bugs.webkit.org/show_bug.cgi?id=266801
<rdar://problem/120022893>
Reviewed by Antti Koivisto.
Do not disconnect list marker and the associated list item when they are
embedded in a list element (e.g. <div><ul><li> vs. <div><li>) -and they are not
positioned inside.
This quirky behavior matches both Chrome and legacy line layout.
