<!-- reasoning:
|
|
|
|
Section 9.1.1:
|
|
# There is at most one viewport per canvas
|
|
-> http://www.w3.org/TR/CSS21/visuren.html#q2
|
|
|
|
Section 2.3.1:
|
|
# the term canvas describes "the space where the formatting
|
|
# structure is rendered."
|
|
-> http://www.w3.org/TR/CSS21/intro.html#q4
|
|
|
|
Section 2.3, item 5:
|
|
# From the annotated document tree, generate a formatting
|
|
# structure.
|
|
-> http://www.w3.org/TR/CSS21/intro.html#processing-model
|
|
|
|
Section 2.3, item 1:
|
|
# Parse the source document and create a document tree.
|
|
-> http://www.w3.org/TR/CSS21/intro.html#processing-model
|
|
|
|
...therefore is a viewport per rendered document. Since there are
|
|
two documents on this page (the main one and the one in the
|
|
object) there are two viewports.
|
|
|
|
The question becomes, what size is the viewport on the object
|
|
element. The spec doesn't define this, but if we consider the
|
|
desired results of the following proposed rule:
|
|
|
|
@viewport { overflow: scroll; }
|
|
|
|
...I don't think it makes sense for the viewport to be anything
|
|
other than the size of the object element's box.
