13215 - child elements placed outside parent elements bounding rectangle are not erased when element is moved via javascript

Status: VERIFIED DUPLICATE of bug 13213

(Core Graveyard :: GFX, defect, P3)

Description

[Dan203]

When an element has a child element that is placed outside it's bounding
rectangle the child element is not erased properly when the parent element is
moved via javascript. This causes the screen to be cluttered with trash, that
can only be erased by minimizing the browser window.

Patrick, this is a compositor issue. Child views are allowed to stick outside
their parent view, and that means when the parent moves its child views that
stick outside and are visible need repainting as well

Wow, this also seems to affect view hit testing as well. A simple, is click in 
parent isn't good enough. If one of the little boxes is dragged outside the big 
box, they can no longer be dragged. Who knew?

Are this bug and Bug 13213 related? The trash only seems to come from things 
hanging from the top or left side of an object. Bug 13213 is a bug where child 
elements placed outside of their parent's top or left side do not register 
events properly. Should we make these two bugs dependant on each other?

Renders correctly with 5/17/2000 build on WINNT. However, after dragging the 
child elements outside the parent elements bounding box I can no longer click on 
the child element. 

I am marking this FIXED since the event problem is separate and covered by bug 
13213

This bug is back in the 7/24 build so I'm reopening it.

This bug has been marked "future" because the original netscape engineer working 
on this is over-burdened. If you feel this is an error, that you or another 
known resource will be working on this bug,or if it blocks your work in some way 
-- please attach your concern to the bug for reconsideration.

This bug is effecting my work on the image map editor for Composer. The image 
map editor is written completely in javascript, with no native C++ code, so it 
is impossible for me to remedy this problem on my own (my C++ skills are very 
limited). I know it is not an extremely high priority, but it should be fixed 
before release.
