           Summary: Overlapping table cells... webkit doesn't always do
                    reasonable things
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
               URL: http://shelleyandjosh.com/tablecellspan.html
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Minor
          Priority: P3
         Component: Tables
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jestelle at google.com


We came across some ugly HTML, where a <table> was defined using rowspan and
colspan on some cells such that two cells effectively overlapped.  What Chrome
did in this case was quite strange, where one of the images in a cell actually
rendered partially outside the bounds of the table.

Here's an example:

Firefox seems to do something more reasonable.

Note: http://www.w3.org/TR/html401/struct/tables.html#h-11.2.6.1 
does say: 
Defining overlapping cells is an error. User agents may vary in how they handle
this error (e.g., rendering may vary)

So my HTML does contain an error.

It just seems that Firefox more gracefully deals with this than Webkit does. 
Should Webkit do something nicer?
