/* This test has different behavior depending on the type of scrollbar used.
* We want the scrollbar to be visible. When overlay scrollbars are used,
* they should be visible even when #cover gets between #outer and #content,
* but for non-overlay scrollbars, that would cover them so we disable the
* cover.
