Description Daniel Bates 2018-11-05 15:04:40 PST 
Seen on iOS 12.

Perform the following:

1. Visit <http://www.microconcepts.com.au/italkaussie/data/italkaussiehelp-en.htm>.
2. Click one of the list item hyperlinks at the top of the page, e.g. Sounds.

Then nothing happens. But the page should have scrolled to section Sounds.

Comment 2 Daniel Bates 2018-11-05 15:07:07 PST 
Notice that the web page with the hyperlinks is in a frame loaded in a frames. If you visit the page directly <http://users.tpg.com.au/mpinnuck/iTalkAussie/Data/iTalkAussieHelp-en.htm> and click one of the hyperlinks then we scroll to the section as expected. So, we do not seem to scroll to anchors in a framed page. And this behavior is consistent with the failure of  test http/tests/navigation/anchor-frames-same-origin.html on iOS.

This regressed in iOS 6.

Disregard this remark.

Pretty sure this is about the "if (delegatesScrolling())" checks in coordinate conversion methods. See bug 164512, bug 176451 etc.
