Replying to [comment:2 snover]:
test case. Not actually sure this is a jQuery bug though.
Not sure what is considered a bug. Certainly this is not caused by behavior inherent in jQuery, but rather in Webkit.
As you can see (and perhaps have already tested), if you set the styles of the
.inner manually in CSS instead of via animation, the incorrect behavior is the same. http://jsfiddle.net/ZHNKf/3/
Changing the width of
1px gives the proper display of the outer container. http://jsfiddle.net/ZHNKf/2/
So it is only a jQuery issue in the sense that it endeavors to correct cross-browser issues. Certainly low priority since a workaround is simple. ''(Simpler than the one I came up with in the SO post from my nascent jQuery days.)''
If it is beyond the scope of jQuery's mission, then it ought to be closed.
