           Summary: HTML OBJECT given height:150px and width:300px by
                    default?
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
               URL: http://www.winserver.com/public/aup/default.htm
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jon at chromium.org

This is blocking Chromium see
http://code.google.com/p/chromium/issues/detail?id=2210

For some reason this object which has no visible representation is given a
default height and width.  This results in the rest of the content of the page
being substantially lower than expected on the page.  Unfortunately, a popular
documentation tool generates these pages.  Using CSS to explicitly set a width
and height resolves the problem.

Other browsers tested:
     Safari 3: Not Tested
    Firefox 3: Not Tested
         IE 7: Not Tested
         IE 6: OK
  Firefox 1.5: OK
   Opera 9.27: OK
 K-meleon 1.2: OK

o What steps will reproduce the problem?

Create a simple web page and add <object> tag to after the <BODY> tag and 
before some viewable display you EXPECT to be at the top of the page. 

Example:

<html>
<head>
<style>body {margin: 5px; border: 2px solid black;}</style>
</head>
<body>
<object></object>
<H2>Welcome to whatever...............</H2>
</body>
</html>

Open the page with Chrome.

o What is the expected result? 

The <H2> tag is rendered at the top of the page.

o What happens instead?

It appears CHROME is given <OBJECT> some (random?) width and height and is 
rendering the <H2> at some location other than the top.

The workaround was to get the object a default style height and width.

OBJECT {
  width: 0px; height: 0px;
}

Attached is the screen shot for the above example.

NOTE: THIS IS IMPORTANT.

Many people use HTMLHELP to create Windows CHM Help files for their 
products and they may also copy the *.HTM source file to their WEB SITE for 
online viewing.  Just like we do at the http://www.winserver.com/aupinfo 
url.     I suggest only Safari and Chrome will have this problem.
