Make offsetTop/Left handle a relative positioned inline offsetParent correctly
https://bugs.webkit.org/show_bug.cgi?id=276275
Reviewed by Antti Koivisto.
Let's take relatively positioned inline box into account when computing
a descendant's offsetTop/Left.
In case of inline formatting context, the incoming "startPoint" is always
relative to
the root block container, however offsetTop/Left is supposed to be relative to
the positioned ancestor (offsetParent)
which is also relative to the root block container.
e.g. <div>text<span style="position: relative"><img>
b________________________ root block container (<div>)
| i__________________ relatively positioned inline box (<span
style="position: relative;">) -> offsetParent
|text |x_____
| || img |
| ||_____|
|
Where [x] point is relative to [b] but what we are looking for here is [x]
relative to [i] as <span> is relatively positioned.
