<!-- This element is just to be sure the scrollframe's "contain:paint"
|
|
styling is actually having an effect. "contain:paint" should make the
|
|
scrollframe become a containing block for this fixed-pos element, and
|
|
then this element will position itself off the bottom of the
|
|
scrollframe and will be entirely clipped. If we fail to honor
|
|
"contain:paint" for some reason, then this element will instead use
|
|
the *viewport* as its containing block, and it'll show up in the
|
|
reftest snapshot and cause the reftest to fail. -->
