102678 - getComputedStyle returns wrong width for elements wider than the browser window

Status: RESOLVED INVALID

(Core :: DOM: CSS Object Model, defect)

Description

[nick]

If there is a element on a page which is wider than the browser window, for
example a very large image, getComputedStyle returns the wrong width for that
element. It seems that the width returned is the width of the part of the
element that is visible on screen.

Another one for you, Boris :-)

The <div> is _not_ wider than the window.  It is in fact exactly the width of
the window (minus the body's margins).  The image overflows the <div> (try
putting a border on the div to see this; also try setting a negative right
margin on the div to see the effect).

getComputedStyle() is correctly reporting the div's width.
getComputedStyle() on the image itself produces the right value (1200px), by the
way.

So I'm not sure what the bug is here.  Resolving invalid, but please reopen if I
missed something.
