            Bug ID: 157577
           Summary: getBoundingClientRect should use the first rect if all
                    rects are empty
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML DOM
          Assignee: webkit-unassigned at lists.webkit.org

Test

http://software.hixie.ch/utilities/js/live-dom-viewer/saved/4189

<!DOCTYPE html>
<div id=x>123</div>
<script>
var r = new Range();
r.setStart(x.firstChild, 1);
r.setEnd(x.firstChild, 1);
w(r.getBoundingClientRect());
</script>

Actual result:

log: object "[object ClientRect]" (6 props: top=0, right=0, bottom=0, left=0...)

Expected result:

log: object "[object ClientRect]" (6 props: top=8, right=16, bottom=26, left=16...)
(this is what I get in Chromium, but actual numbers might depend on fonts etc.)
