287823 - Triple right padding until redrawing, in nested divs, overflow=anything but visible, and container w/o padding

Status: RESOLVED INVALID

(Core :: Layout: Block and Inline, defect)

Description

[David]

User-Agent:       Mozilla/5.0 (compatible; Konqueror/3.4; Linux; es) KHTML/3.4.0 (like Gecko)
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; es-ES; rv:1.7.6) Gecko/20050322 Firefox/1.0.2

If a parent <div> has padding equal to 0 and overflow is set to anything but  
visible, and if the child <div> has overflow set to anything but visible, then  
the child <div> shows a right padding about 3 times larger than its normal  
padding.  

Reproducible: Always

Steps to Reproduce:
1. Load a web page with this: <div class="a"><div  
class="b"><div>test</div></div></div>  
2. The first div (a) should have "padding:0; overflow: hidden;"  
3. The second div (b) should have "padding: 10px; overflow: hidden;"  
Actual Results:  
The second div (b) has a right padding about 3 times longer than normal.  
Redrawing the window shows the normal behavior.  

Expected Results:  
The second div (b) should have a right padding equal to the top, left and 
bottom padding. 
Redrawing the window should not modify any behavior. 

Tested on Firefox 1.0.2 on Windows and Linux. 
An easy way to redraw the window is resizing the font, resizing the window, 
etc... 
Overflow can be set to auto, hidden or scroll with the same behavior. 
Konqueror 3.4.0 and IE6 are working as expected.

I can't reproduce this with a current trunk build (based on Gecko 1.8beta2,
basically).  David, any chance of trying a trunk build and seeing whether the
problem is still there?

OK, on Gecko 1.8beta2 it works.
