40494 - Outer borders of absolute positioned layers are wrong

Status: VERIFIED FIXED

(Core :: XUL, defect, P3)

Description

[Rob Kaper]

When using the "padding" property for layers, the outer borders are positioned
wrong. It looks as if the padding size is added to the position given by the CSS
declarations.

For example, I have a layer with right: 10px and padding: 5px. It's right border
however is positioned zero pixels from the right. (width - 10px + (2 * 5px)).

Check
http://capsi.cx/ with both M11 and a recent nightly build to compare. (there are
a lot of rendering issues that have been broken since droppping native toolkits
after M11, however this problem seems to have been introduced later, it was not
in M12-14 IIRC).

It looks like it is yet another problem with gfx scrollbars and absolutely 
positioned elements. We have 2 symptoms here:
- Make the window small enough: the vertical scrollbar from the center block 
touches the right edge of the window. There should be a 10px border.
- The bottom block overlays the center block. There should be a 5px border 
between them.

It's probably a dup of bug 23806 and it could be related to bug 21899.
Reassigned to trudelle, marked dependency on the meta bug 38639 and proposed for 
nsbeta2. I think that the problems with gfx scrollbars and absolutely positioned 
elements really should be fixed for the next milestone. It's been a nasty 
regression since M15/beta1 for many well-formed CSS pages.
