           Summary: CSS3 transition from width/height auto causes
                    transition from width/height 0
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: webkit at chilon.net


1. Give div width "auto" and a fixed height.
2. Add content to div such that it has width 10px
3. Set css width transition on div.
4. Set div width to 400p.

Expected results:

The draft doesn't say anything about transitions from/to auto so I'd expect no transition to occur and for the div to immediately grow in size.

Actual results:

The div immediately shrinks to a width of 0 and then grows in size to 400px. This is pretty ugly.
