            Bug ID: 235561
           Summary: ResourceTiming should have an entry for iframes that
                    change source
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Frames
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: noam at webkit.org

When an iframe is loaded, it receives a ResourceTiming entry. however, when the src changes later, it doesn't receive a new one.
This was previously vague in the spec, new spec PR clarifies that when a frame navigation is container-initiated it should create an RT entry.

See https://github.com/whatwg/html/pull/7531 & https://github.com/w3c/resource-timing/issues/316
and WPT: https://github.com/web-platform-tests/wpt/pull/32490

Chromium bug: https://bugs.chromium.org/p/chromium/issues/detail?id=1290721
Firefox behavior is according to the new spec addition.
