           Summary: The baseline of an 'inline-table' is the baseline of the
                    first row of the table
           Product: WebKit
           Version: 525.x (Safari 3.2)
          Platform: PC
               URL: http://www.gtalbot.org/BrowserBugsSection/Safari3Bugs/ba
                    seline-inline-table-vertical-align.html
        OS/Version: Windows XP
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: browserbugs at gtalbot.org


Description: 
In Safari 3.2 build 525.26.13, the baseline of an 'inline-table' is NOT the
baseline of the first row of the table. 
According to CSS 2.1, the baseline of an 'inline-table' should be the baseline
of the first row of the table.

Steps to reproduce:
Load provided URL

Expected results:
__Baseline_of_first_row_of_table__ should be vertically aligned with ___text
baseline___ on both sides. The underscore characters of the anonymous text
nodes should adjoin, should meet, should vertically line up with the underscore
characters of the cell of first row of inline-table. 

Actual results in Konqueror 4.1.3 and in Safari 3.2 build 525.26.13:
The margin bottom edge of the inline-table is aligned with ___text baseline___
on both sides. The underscore characters of the anonymous text nodes do not
adjoin, do not meet, do not vertically line up with the underscore characters
of the cell of first row of inline-table. 

References: 
"(...) The baseline of an 'inline-table' is the baseline of the first row of
the table."

"The 'vertical-align' property of each table cell determines its alignment
within the row. (...) The baseline of the cell is put at the same height as the
baseline of the first of the rows it spans (...)"

- Internet Explorer 8 pre-RC1 Partner Build 18344, Firefox 3.0.5, Opera 9.63,
Opera 10.0 alpha build 1229 all pass the provided testcase.

- I searched for a DUPLICATE and did not find any
- The component for this bug could have been Layout and Rendering; make change
if necessary
- This bug may be dependent on bug 4350 (Implement baseline alignment support
for table cells)
- This bug has also been filed for Konqueror at
