            Bug ID: 176699
           Summary: Older versions should adopt newer version's
                    expectations on mac
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
          Assignee: webkit-unassigned at lists.webkit.org

In https://bugs.webkit.org/show_bug.cgi?id=174472, test expectation inheritance for Mac was modified so it was more in-line with other platforms.  There was an aspect of this test inheritance, however, which should be retained to make incrementing versions easier.  Consider El Capitan as we transition to High Sierra:

If test expectation inheritance looks like this for El Capitan:

mac-add-elcapitan-wk2 => mac-elcapitan => mac-sierra-wk2 => mac-sierra => mac-wk2 => mac => wk2

Then we can move any Sierra/El Capitan expectations into mac-sierra, and general High Sierra expectations into Mac (since such expectations will likely apply to future operating systems as well).  Before r219507, this was the technique used.  However, general mac overrode version specific expectations before r219507 (which is definitely incorrect).  See the ChangeLog of <https://trac.webkit.org/changeset/219507/webkit> for details.
