           Summary: CSS transitions on opacity fail when used with
                    visibility in certain circumstances
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P3
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: shawn at frozen-o.com


I'll attach the test case momentarily, which will hopefully explain things a
bit more. I have an element in the page with visibility of hidden. A function
then runs through the following steps:

1. take the element
2. make it visible
3. yet transparent
4. then set the transition
5. and then have it fade from opacity of 0 to 1 over one second

Instead, it appears instantly.

The test case file includes of couple of other functions, similarly written, in
which the element fades in as desired. In one instance, the element simply
starts off with the opacity preset to 0. In the other, it just breaks up the
function into two parts by setting the WebkitTransition and destination opacity
from within an anonymous function called from a setTimeout call with a delay of
0.
