Bug 191284 – [iOS] REGRESSION: Fragment navigation inside cross-origin frameset frame does not work

• Status: NEW
• Component: Frames

[Daniel Bates]

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.

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.

[Daniel Bates]

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.
