           Summary: image in the center column displays incorrectly
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
               URL: http://blog.sina.com.cn/u/4bf6606e01008spa
        OS/Version: Windows XP
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Plug-ins
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: help.improve.safari at gmail.com


I Steps:
 Go to http://blog.sina.com.cn/u/4bf6606e01008spa

 II Issue:
 image in the center column displays incorrectly

 III Conclusion:
 This issue is caused by the calculation of table height in webkit/FF3. In this
case there are two embed objects in a table, the table's height is specified to
300px, the 1st embed's height is not specified and the second embed's height is
specified to 300px, so:

 In IE/Opera, the finally height of table is 300px (height of 1st embed object
is ignored)
 In webkit/FF3, the 1st embed object has a default height, so the final height
of table = 1st embed's default height + 2nd embed's height > 300px. This causes
the table's height is more bigger and the background image repeats a little

 III Other Browsers:
 IE7: ok
 FF3: not ok

 IV Nightly tested: 37382
