48653 - abs. pos. within rel. pos. doesn't work [ABS POS]

Status: VERIFIED WORKSFORME

(Core :: Layout, defect, P3)

Description

[Jack Dignan]

Positioning an item using CSS absolute positioning within a context defined 
with relative positioning does not work; the item is positioned absolutely 
using screen coordinates instead of the context in which it was defined. For 
example,

<span style="position:relative">
hello, world.
<span style="position:absolute;top:20px">
20 pixels down
</span>
</span>

The text "20 pixels down" is positioned 20 pixels from the top of the screen, 
not from the period in "hello, world."

In addition to this problem, any use of "position:relative" causes the browser 
to crash when the page is reloaded.

over to style system

[Jeffrey Baker]

The crash is covered by bug 46356.  The layout problem is not.

Comment 4

[Marc Attinasi]

This is a layout problem: the style information is correct. Also, attaching a 
complete testcase...

[Marc Attinasi]

Attachment: Complete testcase: just like the reporter's example

I think this page is working correctly, except that the default "left: auto" 
isn't offsetting the abs. pos. element correctly.  I've submitted this as bug 
53052. 

This bug is about what box the abs. pos. element is offset from, the 
body (incorrect) or the containing block (the rel. pos. element, correct.)

(spam: changed the summary to use abbreviations so it fits in a bugzilla query 
page)
