Description Ryosuke Niwa 2010-11-01 16:31:26 PDT
window.getComputedStyle returns text-align: -webkit-auto instead of text-align: left / text-align: right when queried against a node when text-align property is not explicitly specified.

For example, suppose we have:
<div id="mydiv" contentEditable>foo</div>

The following script gives -webkit-auto:
window.getComputedStyle(document.getElementById('mydiv'))['textAlign']

Demo:

I was looking into whether we can remove -webkit-auto wholesale in favor of start.  These are basically the same [as far as I can tell] except for a case in CSSStyleSelector::adjustRenderStyle() which has a special case for TH tags introduced in http://trac.webkit.org/changeset/20889 .

So I looked back at when -webkit-auto was introduced into the tree, it used to be called -khtml-auto and before that -konq-auto , relevant CLs:

This bug is OBE with bug 79914 already applied. The only thing that remains is removing support for using the older -webkit-auto value, for which I've filed a bug 98126.
