"observeDifferentDocumentNavigation" might be a more descriptive name. The intent of this change is to initialize the page scale factor to minimum on initial visit of any document without a viewport tag (and never again thereafter). We clear this boolean to false when navigating to a new document as a note that we need to initialize the page scale as soon as we learn the content width. But we don't want to touch the boolean if it's a same-page navigation.

The intent of this change is to initialize the page scale factor to minimum on initial visit of any document without a viewport tag (and never again thereafter). We clear this boolean to false when navigating to a new document as a note that we need to initialize the page scale as soon as we learn the content width. But we don't want to touch the boolean if it's a same-page navigation. Updated patch according to comments above.

If that information were pushed there, then didCommitLoad would work. It seems trivial to add such a boolean. I would do that. See the two callsites in FrameLoaderClientImpl.cpp. Name the boolean isNavigationWithinPage.
