Description Arne 2008-09-20 04:39:03 PDT 
A span-tag at the end of a paragraph, e.g:
<p>Text <span></span></p>
Does not have a proper offsetLeft when there is a whitespace between the text and span-tag.

Testcase

A testcase for this, that will print an error if a strange wrong offsetLeft is received.

It passes on FireFox/3.0.1.

I am able to reproduce this bug based on attached test case and Safari show extra line (Expected offsetLeft for empty span-tag...), which is not present in other browsers as can be seen from attached screenshot. I am changing "bug" status to NEW. Thanks!

This is about WebKit's useTrailingWhitespaceMeasuringOptimization (see TextUtil::width)
