Bug 1421105 implements "column-span" for block and inline frames only. <fieldset> are still using InitAndWrapInColumnSetFrameIfNeeded() to construct column hierarchy, which is unaware of "column-span".

Per spec, "Note: Column boxes do not become the containing block for
elements with position: fixed or position: absolute. The containing
block is the multicol container, it being the principal box."
https://drafts.csswg.org/css-multicol-1/#the-multi-column-model
contentFrame and contentFrameTop are different only if fieldset has
multicol layout. In that case, contentFrameTop is nsColumnSetFrame (or
ColumnSetWrapperFrame after applying Part 2 with
layout.css.column-span.enabled=true).
