Bug 13476 – Line box is misplaced for an anchor containing a positioned image

• Status: RESOLVED
• Resolution: FIXED
• Component: Layout and Rendering

[David Kilzer (:ddkilzer)]

* SUMMARY
When using the WebInspector, inspecting an anchor that contains a positioned image causes the red hightlight rect to be drawn in the wrong place (e.g., where the image would be if it were not positioned).

* STEPS TO REPRODUCE
1. Open Safari/WebKit.
2. Open the attached test case.
3. Right-click on the image, select "Inspect Element".

* EXPECTED RESULTS
The red highlight should be drawn around the image on the screen.

* ACTUAL RESULTS
The red highlight draws where the image would be if it was not set to "position: absolute".

* REGRESSION
I doubt that this is a regression from shipping Safari, but I don't have an easy way to test it without the Web Inspector.

* NOTES
- The red highlight rect is also mispositioned if the style is "position: relative" instead of "position: absolute".  The "position: fixed" style is also mispositioned, but the "position: static" style is not.
