"Show pinned tabs in a separate row" was ignored while "Multiple rows" was on, because the pinned row explicitly excluded horizontal layouts with multiple rows. The two options are independent, so the pinned row now shows whenever some but not all tabs are pinned, and each row wraps on its own. With the rows split, dropping a tab on the pinned row pins it and keeps it in the pinned group, and dropping it on the other row unpins it.
