36298 - fixed positioning CSS2 elements overlap: footer wrong

Status: VERIFIED DUPLICATE of bug 4209

(Core Graveyard :: Embedding: ActiveX Wrapper, defect, P3)

Description

[Jos.vandenOever]

Fixed positioning of elements with the example given in the W3C definition gives
overlapping elements.
The footer is drawn at the top and overlaps with the header.
The main and sidebar also overlap with the header, but this is due to the
headers small size.

if this sample is valid, note also that it overwrites the right scrollbar and
that scrolling is impossible.

-> style system?

Comment 4

[Blake Ross]

sorry, forgot to reassign...assigning to owner of style system, troy feel free 
to fix this if wrong

Reassigning back to layout

Comment 6

[troy]

This is a DUP of bug #4209. There are several compositor related bugs concerning 
fixed positioning

Note that as a workaround for the time being you can specify a background color 
for each of the fixed positioned elements and then things paint is a sensible 
fashion

With background painting the footer is still placed at the top of the page. It
is painted over the other elements.
See attachement.

You must not be using the latest build. I took your example and made specified 
background colors for each absolutely positioned element and it looked fine

Marking verified dup of 4209.

This is mostly fixed by the fix to bug 4209, but R.K.Aa's comment about the
non-functional scrollbar remains true.
